Changelog
Daniel (6 September 2006)
- Ravi Pratap and I have implemented HTTP Pipelining support. Enable it for a
multi handle using CURLMOPT_PIPELINING and all HTTP connections done on that
handle will be attempted to get pipelined instead of done in parallell as
they are performed otherwise.
As a side-effect from this work, connections are now shared between all easy
handles within a multi handle, so if you use N easy handles for transfers,
each of them can pick up and re-use a connection that was previously used by
any of the handles, be it the same or one of the others.
This separation of the tight relationship between connections and easy
handles is most noticable when you close easy handles that have been used in
a multi handle and check amount of used memory or watch the debug output, as
there are times when libcurl will keep the easy handle around for a while
longer to be able to close it properly. Like for sending QUIT to close down
an FTP connection.
This is a major change.

Pass a pointer to whatever you want passed to the curl_socket_callback's forth
argument, the userp pointer. This is not used by libcurl but only passed-thru
as-is. Set the callback pointer with \fICURLMOPT_SOCKETFUNCTION\fP.
.IP CURLMOPT_PIPELINING
Pass a long set to 1 to enable or 0 to disable. Enabling pipelining on a multi
handle will make it attempt to perform HTTP Pipelining as far as possible for
transfers using this handle. This means that if you add a second request that
can use an already existing connection, the second request will be \&"piped"
on the same connection rather than being executed in parallell. (Added in
7.16.0)
