For a greater explanation of the format please see RFC3986.
If the given URL lacks the scheme, or protocol, part ("http://" or "ftp://"
etc), libcurl will attempt to resolve which protocol to use based on the
given host mame. If the protocol is not supported, libcurl will return
(\fICURLE_UNSUPPORTED_PROTOCOL\fP) when you call \fIcurl_easy_perform(3)\fP
or \fIcurl_multi_perform(3)\fP. Use \fIcurl_version_info(3)\fP for detailed
information on which protocols are supported.
If the given URL lacks the scheme (such as "http://" or "ftp://" etc) then
libcurl will attempt to resolve the protocol based on the given host name,
which may be one of the following:
HTTP, FTP, DICT, LDAP, IMAP, POP3 or SMTP
(POP3 and SMTP added in 7.30.1)
Should the protocol, either that specified by the scheme or deduced by libcurl
from the host name, not be supported by libcurl then
(\fICURLE_UNSUPPORTED_PROTOCOL\fP) will be returned from either the
\fIcurl_easy_perform(3)\fP or \fIcurl_multi_perform(3)\fP functions when you
call them. Use \fIcurl_version_info(3)\fP for detailed information of which
protocols are supported by the build of libcurl you are using.
