-%%% Description : Load balancer process for HTTP client connections.
-%%%
-%%% Created : 11 Oct 2003 by Chandrashekhar Mullaparthi <chandrashekhar.mullaparthi@t-mobile.co.uk>

-%% @version 1.5.2
-%% @doc The ibrowse application implements an HTTP 1.1 client. This
-%% module implements the API of the HTTP client. There is one named
-%% process called 'ibrowse' which assists in load balancing and maintaining configuration. There is one load balancing process per unique webserver. There is
-%% one process to handle one TCP connection to a webserver
-%% (implemented in the module ibrowse_http_client). Multiple connections to a
-%% webserver are setup based on the settings for each webserver. The
-%% ibrowse process also determines which connection to pipeline a
-%% certain request on. The functions to call are send_req/3,
-%% send_req/4, send_req/5, send_req/6.
-%%
-%% <p>Here are a few sample invocations.</p>
-%%
-%% <code>
-%% ibrowse:send_req("http://intranet/messenger/", [], get).
-%% <br/><br/>
-%%
-%% ibrowse:send_req("http://www.google.com/", [], get, [],
-%% [{proxy_user, "XXXXX"},
-%% {proxy_password, "XXXXX"},
-%% {proxy_host, "proxy"},
-%% {proxy_port, 8080}], 1000).
-%% <br/><br/>
-%%
-%%ibrowse:send_req("http://www.erlang.org/download/otp_src_R10B-3.tar.gz", [], get, [],
-%% [{proxy_user, "XXXXX"},
-%% {proxy_password, "XXXXX"},
-%% {proxy_host, "proxy"},
-%% {proxy_port, 8080},
-%% {save_response_to_file, true}], 1000).
-%% <br/><br/>
-%%
-%% ibrowse:send_req("http://www.erlang.org", [], head).
-%%
-%% <br/><br/>
-%% ibrowse:send_req("http://www.sun.com", [], options).
-%%
-%% <br/><br/>
-%% ibrowse:send_req("http://www.bbc.co.uk", [], trace).
-%%
-%% <br/><br/>
-%% ibrowse:send_req("http://www.google.com", [], get, [],
-%% [{stream_to, self()}]).
-%% </code>
-%%
-%% <p>A driver exists which implements URL encoding in C, but the
-%% speed achieved using only erlang has been good enough, so the
-%% driver isn't actually used.</p>

-%% If fun/1, the connection handling process will repeatedly call the fun with the supplied state until it returns an error or eof. <pre>Fun(State) = {ok, Data} | {ok, Data, NewState} | eof</pre>

-%% For a description of SSL Options, look in the <a href="http://www.erlang.org/doc/apps/ssl/index.html">ssl</a> manpage. If the
-%% HTTP Version to use is not specified, the default is 1.1.
-%% <br/>
-%% <p>The <code>host_header</code> option is useful in the case where ibrowse is
-%% connecting to a component such as <a
-%% href="http://www.stunnel.org">stunnel</a> which then sets up a
-%% secure connection to a webserver. In this case, the URL supplied to
-%% ibrowse must have the stunnel host/port details, but that won't
-%% make sense to the destination webserver. This option can then be
-%% used to specify what should go in the <code>Host</code> header in
-%% the request.</p>
-%% <ul>
-%% <li>The <code>stream_to</code> option can be used to have the HTTP
-%% response streamed to a process as messages as data arrives on the
-%% socket. If the calling process wishes to control the rate at which
-%% data is received from the server, the option <code>{stream_to,
-%% {process(), once}}</code> can be specified. The calling process
-%% will have to invoke <code>ibrowse:stream_next(Request_id)</code> to
-%% receive the next packet.</li>
-%%
-%% <li>When both the options <code>save_response_to_file</code> and <code>stream_to</code>
-%% are specified, the former takes precedence.</li>
-%%
-%% <li>For the <code>save_response_to_file</code> option, the response body is saved to
-%% file only if the status code is in the 200-299 range. If not, the response body is returned
-%% as a string.</li>
-%% <li>Whenever an error occurs in the processing of a request, ibrowse will return as much
-%% information as it has, such as HTTP Status Code and HTTP Headers. When this happens, the response
-%% is of the form <code>{error, {Reason, {stat_code, StatusCode}, HTTP_headers}}</code></li>
-%%
-%% <li>The <code>inactivity_timeout</code> option is useful when
-%% dealing with large response bodies and/or slow links. In these
-%% cases, it might be hard to estimate how long a request will take to
-%% complete. In such cases, the client might want to timeout if no
-%% data has been received on the link for a certain time interval.</li>
-%%
-%% <li>
-%% The <code>connect_timeout</code> option is to specify how long the
-%% client process should wait for connection establishment. This is
-%% useful in scenarios where connections to servers are usually setup
-%% very fast, but responses might take much longer compared to
-%% connection setup. In such cases, it is better for the calling
-%% process to timeout faster if there is a problem (DNS lookup
-%% delays/failures, network routing issues, etc). The total timeout
-%% value specified for the request will enforced. To illustrate using
-%% an example:
-%% <code>
-%% ibrowse:send_req("http://www.example.com/cgi-bin/request", [], get, [], [{connect_timeout, 100}], 1000).
-%% </code>
-%% In the above invocation, if the connection isn't established within
-%% 100 milliseconds, the request will fail with
-%% <code>{error, conn_failed}</code>.<br/>
-%% If connection setup succeeds, the total time allowed for the
-%% request to complete will be 1000 milliseconds minus the time taken
-%% for connection setup.
-%% </li>
-%% </ul>
