+HTTP/2 with curl
+================
+
+[HTTP/2 Spec](https://www.rfc-editor.org/rfc/rfc7540.txt)
+[http2 explained](http://daniel.haxx.se/http2/)
+
+Build prerequisites
+-------------------
+  - nghttp2
+  - OpenSSL, NSS, GnutTLS or PolarSSL with a new enough version
+
+[nghttp2](https://nghttp2.org/)
+-------------------------------
+
+libcurl uses this 3rd party library for the low level protocol handling
+parts. The reason for this is that HTTP/2 is much more complex at that layer
+than HTTP/1.1 (which we implement on our own) and that nghttp2 is an already
+existing and well functional library.
+
+We require at least version 1.0.0.
+
+Over an http:// URL
+-------------------
+
+If `CURLOPT_HTTP_VERSION` is set to `CURL_HTTP_VERSION_2_0`, libcurl will
+include an upgrade header in the initial request to the host to allow
+upgrading to HTTP/2.
+
+Possibly we can later introduce an option that will cause libcurl to fail if
+not possible to upgrade. Possibly we introduce an option that makes libcurl
+use HTTP/2 at once over http://
+
+Over an https:// URL
+--------------------
+
+If `CURLOPT_HTTP_VERSION` is set to `CURL_HTTP_VERSION_2_0`, libcurl will use
+ALPN (or NPN) to negotiate which protocol to continue with. Possibly introduce
+an option that will cause libcurl to fail if not possible to use HTTP/2.
+Consider options to explicitly disable ALPN and/or NPN.
+
+ALPN is the TLS extension that HTTP/2 is expected to use. The NPN extension is
+for a similar purpose, was made prior to ALPN and is used for SPDY so early
+HTTP/2 servers are implemented using NPN before ALPN support is widespread.
+
+SSL libs
+--------
+
+The challenge is the ALPN and NPN support and all our different SSL
+backends. You may need a fairly updated SSL library version for it to
+provide the necessary TLS features. Right now we support:
+
+  - OpenSSL:  ALPN and NPN
+  - NSS:      ALPN and NPN
+  - GnuTLS:   ALPN
+  - PolarSSL: ALPN
+
+Multiplexing
+------------
+
+Starting in 7.43.0, libcurl fully supports HTTP/2 multiplexing, which is the
+term for doing multiple independent transfers over the same physical TCP
+connection.
+
+To take advantage of multiplexing, you need to use the multi interface and set
+`CURLMOPT_PIPELINING` to `CURLPIPE_MULTIPLEX`. With that bit set, libcurl will
+attempt to re-use existing HTTP/2 connections and just add a new stream over
+that when doing subsequent parallel requests.
+
+While libcurl sets up a connection to a HTTP server there is a period during
+which it doesn't know if it can pipeline or do multiplexing and if you add new
+transfers in that period, libcurl will default to start new connections for
+those transfers. With the new option `CURLOPT_PIPEWAIT` (added in 7.43.0), you
+can ask that a transfer should rather wait and see in case there's a
+connection for the same host in progress that might end up being possible to
+multiplex on. It favours keeping the number of connections low to the cost of
+slightly longer time to first byte transferred.
+
+Applications
+------------
+
+We hide HTTP/2's binary nature and convert received HTTP/2 traffic to headers
+in HTTP 1.1 style. This allows applications to work unmodified.
+
+curl tool
+---------
+
+curl offers the `--http2` command line option to enable use of HTTP/2
+
+HTTP Alternative Services
+-------------------------
+
+Alt-Svc is a suggested extension with a corresponding frame (ALTSVC) in HTTP/2
+that tells the client about an alternative "route" to the same content for the
+same origin server that you get the response from. A browser or long-living
+client can use that hint to create a new connection asynchronously.  For
+libcurl, we may introduce a way to bring such clues to the applicaton and/or
+let a subsequent request use the alternate route
+automatically. [Spec](https://tools.ietf.org/html/draft-ietf-httpbis-alt-svc-05)
+
+TODO
+----
+
+  - Provide API to set priorities / dependencies of individual streams
+
+  - Implement "prior-knowledge" HTTP/2 connecitons over clear text so that
+    curl can connect with HTTP/2 at once without 1.1+Upgrade.

-Structs in libcurl

-  1.2 connectdata

-  1.4 Curl_handler
-  1.5 conncache

-  1.7 CookieInfo
-
-==============================================================================
-
-1. The main structs in libcurl
-
-  1.1 SessionHandle
-
-  The SessionHandle handle struct is the one returned to the outside in the
-  external API as a "CURL *". This is usually known as an easy handle in API
-  documentations and examples.
-
-  Information and state that is related to the actual connection is in the
-  'connectdata' struct. When a transfer is about to be made, libcurl will
-  either create a new connection or re-use an existing one. The particular
-  connectdata that is used by this handle is pointed out by
-  SessionHandle->easy_conn.
-
-  Data and information that regard this particular single transfer is put in
-  the SingleRequest sub-struct.
-
-  When the SessionHandle struct is added to a multi handle, as it must be in
-  order to do any transfer, the ->multi member will point to the Curl_multi
-  struct it belongs to. The ->prev and ->next members will then be used by the
-  multi code to keep a linked list of SessionHandle structs that are added to
-  that same multi handle. libcurl always uses multi so ->multi *will* point to
-  a Curl_multi when a transfer is in progress.
-
-  ->mstate is the multi state of this particular SessionHandle. When
-  multi_runsingle() is called, it will act on this handle according to which
-  state it is in. The mstate is also what tells which sockets to return for a
-  specific SessionHandle when curl_multi_fdset() is called etc.
-
-  The libcurl source code generally use the name 'data' for the variable that
-  points to the SessionHandle.
-
-
-  1.2 connectdata
-
-  A general idea in libcurl is to keep connections around in a connection
-  "cache" after they have been used in case they will be used again and then
-  re-use an existing one instead of creating a new as it creates a significant
-  performance boost.
-
-  Each 'connectdata' identifies a single physical connection to a server. If
-  the connection can't be kept alive, the connection will be closed after use
-  and then this struct can be removed from the cache and freed.
-
-  Thus, the same SessionHandle can be used multiple times and each time select
-  another connectdata struct to use for the connection. Keep this in mind, as
-  it is then important to consider if options or choices are based on the
-  connection or the SessionHandle.
-
-  Functions in libcurl will assume that connectdata->data points to the
-  SessionHandle that uses this connection.
-
-  As a special complexity, some protocols supported by libcurl require a
-  special disconnect procedure that is more than just shutting down the
-  socket. It can involve sending one or more commands to the server before
-  doing so. Since connections are kept in the connection cache after use, the
-  original SessionHandle may no longer be around when the time comes to shut
-  down a particular connection. For this purpose, libcurl holds a special
-  dummy 'closure_handle' SessionHandle in the Curl_multi struct to 
-
-  FTP uses two TCP connections for a typical transfer but it keeps both in
-  this single struct and thus can be considered a single connection for most
-  internal concerns.
-
-  The libcurl source code generally use the name 'conn' for the variable that
-  points to the connectdata.
-
-
-  1.3 Curl_multi
-
-  Internally, the easy interface is implemented as a wrapper around multi
-  interface functions. This makes everything multi interface.
-
-  Curl_multi is the multi handle struct exposed as "CURLM *" in external APIs.
-
-  This struct holds a list of SessionHandle structs that have been added to
-  this handle with curl_multi_add_handle(). The start of the list is ->easyp
-  and ->num_easy is a counter of added SessionHandles.
-
-  ->msglist is a linked list of messages to send back when
-  curl_multi_info_read() is called. Basically a node is added to that list
-  when an individual SessionHandle's transfer has completed.
-
-  ->hostcache points to the name cache. It is a hash table for looking up name
-  to IP. The nodes have a limited life time in there and this cache is meant
-  to reduce the time for when the same name is wanted within a short period of
-  time.
-
-  ->timetree points to a tree of SessionHandles, sorted by the remaining time
-  until it should be checked - normally some sort of timeout. Each
-  SessionHandle has one node in the tree.
-
-  ->sockhash is a hash table to allow fast lookups of socket descriptor to
-  which SessionHandle that uses that descriptor. This is necessary for the
-  multi_socket API.
-
-  ->conn_cache points to the connection cache. It keeps track of all
-  connections that are kept after use. The cache has a maximum size.
-
-  ->closure_handle is described in the 'connectdata' section.
-
-  The libcurl source code generally use the name 'multi' for the variable that
-  points to the Curl_multi struct.
-
-
-  1.4 Curl_handler
-
-  Each unique protocol that is supported by libcurl needs to provide at least
-  one Curl_handler struct. It defines what the protocol is called and what
-  functions the main code should call to deal with protocol specific issues.
-  In general, there's a source file named [protocol].c in which there's a
-  "struct Curl_handler Curl_handler_[protocol]" declared. In url.c there's
-  then the main array with all individual Curl_handler structs pointed to from
-  a single array which is scanned through when a URL is given to libcurl to
-  work with.
-
-  ->scheme is the URL scheme name, usually spelled out in uppercase. That's
-  "HTTP" or "FTP" etc. SSL versions of the protcol need its own Curl_handler
-  setup so HTTPS separate from HTTP.
-
-  ->setup_connection is called to allow the protocol code to allocate protocol
-  specific data that then gets associated with that SessionHandle for the rest
-  of this transfer. It gets freed again at the end of the transfer. It will be
-  called before the 'connectdata' for the transfer has been selected/created.
-  Most protocols will allocate its private 'struct [PROTOCOL]' here and assign
-  SessionHandle->req.protop to point to it.
-
-  ->connect_it allows a protocol to do some specific actions after the TCP
-  connect is done, that can still be considered part of the connection phase.
-
-  Some protocols will alter the connectdata->recv[] and connectdata->send[]
-  function pointers in this function.
-
-  ->connecting is similarly a function that keeps getting called as long as the
-  protocol considers itself still in the connecting phase.
-
-  ->do_it is the function called to issue the transfer request. What we call
-  the DO action internally. If the DO is not enough and things need to be kept
-  getting done for the entire DO sequence to complete, ->doing is then usually
-  also provided. Each protocol that needs to do multiple commands or similar
-  for do/doing need to implement their own state machines (see SCP, SFTP,
-  FTP). Some protocols (only FTP and only due to historical reasons) has a
-  separate piece of the DO state called DO_MORE.
-
-  ->doing keeps getting called while issuing the transfer request command(s)
-
-  ->done gets called when the transfer is complete and DONE. That's after the
-  main data has been transferred.
-
-  ->do_more gets called during the DO_MORE state. The FTP protocol uses this
-  state when setting up the second connection.
-
-  ->proto_getsock
-  ->doing_getsock
-  ->domore_getsock
-  ->perform_getsock
-  Functions that return socket information. Which socket(s) to wait for which
-  action(s) during the particular multi state.
-
-  ->disconnect is called immediately before the TCP connection is shutdown.
-
-  ->readwrite gets called during transfer to allow the protocol to do extra
-  reads/writes
-
-  ->defport is the default report TCP or UDP port this protocol uses
-
-  ->protocol is one or more bits in the CURLPROTO_* set. The SSL versions have
-  their "base" protocol set and then the SSL variation. Like "HTTP|HTTPS".
-
-  ->flags is a bitmask with additional information about the protocol that will
-  make it get treated differently by the generic engine:
-
-    PROTOPT_SSL - will make it connect and negotiate SSL
-
-    PROTOPT_DUAL - this protocol uses two connections
-
-    PROTOPT_CLOSEACTION - this protocol has actions to do before closing the
-    connection. This flag is no longer used by code, yet still set for a bunch
-    protocol handlers.
-  
-    PROTOPT_DIRLOCK - "direction lock". The SSH protocols set this bit to
-    limit which "direction" of socket actions that the main engine will
-    concern itself about.
-
-    PROTOPT_NONETWORK - a protocol that doesn't use network (read file:)
-
-    PROTOPT_NEEDSPWD - this protocol needs a password and will use a default
-    one unless one is provided
-
-    PROTOPT_NOURLQUERY - this protocol can't handle a query part on the URL
-    (?foo=bar)
-
-
-  1.5 conncache
-
-  Is a hash table with connections for later re-use. Each SessionHandle has
-  a pointer to its connection cache. Each multi handle sets up a connection
-  cache that all added SessionHandles share by default.
-
-
-  1.6 Curl_share
-  
-  The libcurl share API allocates a Curl_share struct, exposed to the external
-  API as "CURLSH *".
-
-  The idea is that the struct can have a set of own versions of caches and
-  pools and then by providing this struct in the CURLOPT_SHARE option, those
-  specific SessionHandles will use the caches/pools that this share handle
-  holds.
-
-  Then individual SessionHandle structs can be made to share specific things
-  that they otherwise wouldn't, such as cookies.
-
-  The Curl_share struct can currently hold cookies, DNS cache and the SSL
-  session cache.
-
-  
-  1.7 CookieInfo
-
-  This is the main cookie struct. It holds all known cookies and related
-  information. Each SessionHandle has its own private CookieInfo even when
-  they are added to a multi handle. They can be made to share cookies by using
-  the share API.

 possible participation.
 
-New stuff - libcurl
+HTTP/2
+------
+
+- test suite
+
+   Base this on existing nghttp2 server to start with to make functional
+   tests. Later on we can adopt that code or work with nghttp2 to provide ways
+   to have the http2 server respond with broken responses to make sure we deal
+   with that nicely as well.
+
+   To decide: if we need to bundle parts of the nghttp2 stuff that probably
+   won't be shipped by many distros.
+
+- stream properties API
+
+   Provide options for setting priorities and dependencies among the streams
+   (easy handles). They are mostly information set for the stream and sent to
+   the server so we don't have to add much logic for this.
+
+- server push
+
+   Not exactly clear exactly how to support this API-wise, but by adding
+   handles without asking for a resource it could be a way to be prepared to
+   receive pushes in case such are sent. We probably need it to still specify
+   a URL with host name, port etc but we probably need a special option to
+   tell libcurl it is for server push purposes.
+
+- provide option for HTTP/2 "prior knowledge" over clear text
+
+   As it would avoid the roundtrip-heavy Upgrade: procedures when you _know_
+   it speaks HTTP/2.
+
+- provide option to allow curl to default to HTTP/2 only when using HTTPS
+
+   We could switch on HTTP/2 by-default for HTTPS quite easily and it
+   shouldn't hurt anyone, while HTTP/2 for HTTP by default could introduce
+   lots of Upgrade: roundtrips that users won't like. So a separated option
+   alternative makes sense.
+
+SRV records
+-----------
+
+How to find services for specific domains/hosts.
+
+HTTPS to proxy
+--------------
+
+To avoid network traffic to/from the proxy getting snooped on.
+
+curl_formadd()
+--------------
+
+make sure there's an easy handle passed in to `curl_formadd()`,
+`curl_formget()` and `curl_formfree()` by adding replacement functions and
+deprecating the old ones to allow custom mallocs and more
+
+third-party SASL
+----------------
+
+add support for third-party SASL libraries such as Cyrus SASL - may need to
+move existing native and SSPI based authentication into vsasl folder after
+reworking HTTP and SASL code
+
+SASL authentication in LDAP

+...
+
+Simplify the SMTP email

+ A single curl command line may involve one or many URLs. The most common case

+ given URLs.

+ Example, send two GETs:
