+SSL problems
+
+  First, let's establish that we often refer to TLS and SSL interchangeably as
+  SSL here. The current protocol is called TLS, it was called SSL a long time
+  ago.
+
+  There are several known reasons why a connection that involves SSL might
+  fail. This is a document that attempts to details the most common ones and
+  how to mitigate them.
+
+CA certs
+
+  CA certs are used to digitally verify the server's certificate. You need a
+  "ca bundle" for this. See lots of more details on this in the SSLCERTS
+  document.
+
+CA bundle missing intermediate certificates
+
+  When using said CA bundle to verify a server cert, you will experience
+  problems if your CA cert does not have the certificates for the
+  intermediates in the whole trust chain.
+
+SSL version
+
+  Some broken servers fail to support the protocol negotiation properly that
+  SSL servers are supposed to handle. This may cause the connection to fail
+  completely. Sometimes you may need to explicitly select a SSL version to use
+  when connecting to make the connection succeed.
+
+  An additional complication can be that modern SSL libraries sometimes are
+  built with support for older SSL and TLS versions disabled!
+
+SSL ciphers
+
+  Clients give servers a list of ciphers to select from. If the list doesn't
+  include any ciphers the server wants/can use, the connection handshake
+  fails.
+
+  curl has recently disabled the user of a whole bunch of seriously insecure
+  ciphers from its default set (slightly depending on SSL backend in use).
+
+  You may have to explicitly provide an alternative list of ciphers for curl
+  to use to allow the server to use a WEAK cipher for you.
+
+  Note that these weak ciphers are identified as flawed. For example, this
+  includes symmetric ciphers with less than 128 bit keys and RC4.
+
+  References:
+
+  http://tools.ietf.org/html/draft-popov-tls-prohibiting-rc4-01
+  
+Allow BEAST
+
+  BEAST is the name of a TLS 1.0 attack that surfaced 2011. When adding means
+  to mitigate this attack, it turned out that some broken servers out there in
+  the wild didn't work properly with the BEAST mitigation in place.
+
+  To make such broken servers work, the --ssl-allow-beast option was
+  introduced. Exactly as it sounds, it re-introduces the BEAST vulnerability
+  but on the other hand it allows curl to connect to that kind of strange
+  servers.

 2. URL

+ canonical spec.
 
-3. GET a page
+ 2.2 Host
+
+ The host name is usually resolved using DNS or your /etc/hosts file to an IP
+ address and that's what curl will communicate with. Alternatively you specify
+ the IP address directly in the URL instead of a name.
+
+ For development and other trying out situation, you can point out a different
+ IP address for a host name than what would otherwise be used, by using curl's
+ --resolve option:
+
+      curl --resolve www.example.org:80:127.0.0.1 http://www.example.org/
+ 
+ 2.3 Port number
+
+ Each protocol curl supports operate on a default port number, be it over TCP
+ or in some cases UDP. Normally you don't have to take that into
+ consideration, but at times you run test servers on other ports or
+ similar. Then you can specify the port number in the URL with a colon and a
+ number immediately following the host name. Like when doing HTTP to port
+ 1234:
+
+      curl http://www.example.org:1234/
+
+ The port number you specify in the URL is the number that the server uses to
+ offer its services. Sometimes you may use a local proxy, and then you may
+ need to specify that proxy's port number separate on what curl needs to
+ connect to locally. Like when using a HTTP proxy on port 4321:
+
+      curl --proxy http://proxy.example.org:4321 http://remote.example.org/
+
+ 2.4 User name and password
+
+ Some services are setup to require HTTP authentication and then you need to
+ provide name and password which then is transferred to the remote site in
+ various ways depending on the exact authentication protocol used.
+
+ You can opt to either insert the user and password in the URL or you can
+ provide them separately:
+
+      curl http://user:password@example.org/
+
+ or
+
+      curl -u user:password http://example.org/
+
+ You need to pay attention that this kind of HTTP authentication is not what
+ is usually done and requested by user-oriented web sites these days. They
+ tend to use forms and cookies instead.
+
+ 2.5 Path part
+
+ The path part is just sent off to the server to request that it sends back
+ the associated response. The path is what is to the right side of the slash
+ that follows the host name and possibly port number.

  Over an https:// URL
 
   If CURLOPT_HTTP_VERSION is set to CURL_HTTP_VERSION_2, 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 http2.
+  Consider options to explicitly disable ALPN and/or NPN.
+
+  ALPN is the TLS extension that http2 is expected to use. The NPN extension
+  is for a similar purpose, was made prior to ALPN and is used for SPDY so
+  early http2 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
+
+Applications
+
+  We hide http2's binary nature and convert received http2 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 http2
