+%%% This version of the HTTP/1.1 client implements:
+%%% - RFC 2616 HTTP 1.1 client part
+%%% - RFC 2817 Upgrading to TLS Within HTTP/1.1 (not yet!)
+%%% - RFC 2818 HTTP Over TLS
+%%% - RFC 3229 Delta encoding in HTTP (not yet!)
+%%% - RFC 3230 Instance Digests in HTTP (not yet!)
+%%% - RFC 3310 Authentication and Key Agreement (AKA) (not yet!)
+%%% - HTTP/1.1 Specification Errata found at
+%%% http://world.std.com/~lawrence/http_errata.html
+%%% Additionaly follows the following recommendations:
+%%% - RFC 3143 Known HTTP Proxy/Caching Problems (not yet!)
+%%% - draft-nottingham-hdrreg-http-00.txt (not yet!)
+%%%
+%%% Depends on
+%%% - uri.erl for all URL parsing (except what is handled by the C driver)
+%%% - http_lib.erl for all parsing of body and headers
+%%%
+%%% Supported Settings are:
+%%% http_timeout % (int) Milliseconds before a request times out
+%%% http_useproxy % (bool) True if a proxy should be used
+%%% http_proxy % (string) Proxy
+%%% http_noproxylist % (list) List with hosts not requiring proxy
+%%% http_autoredirect % (bool) True if automatic redirection on 30X responses
+%%% http_ssl % (list) SSL settings. A non-empty list enables SSL/TLS
+%%% support in the HTTP client
+%%% http_pipelinesize % (int) Length of pipeline. 1 means no pipeline.
+%%% Only has effect when initiating a new session.
+%%% http_sessions % (int) Max number of open sessions for {Addr,Port}
+%%%
+%%% TODO: (Known bugs!)
+%% - Cache handling
+%% - Doesn't handle a bunch of entity headers properly
+%% - Better handling of status codes different from 200,30X and 50X
+%% - Many of the settings above are not implemented!
+%% - close_session/2 and cancel_request/1 doesn't work
+%% - Variable pipe size.
+%% - Due to the fact that inet_drv only has a single timer, the timeouts given
+%% for pipelined requests are not ok (too long)
+%%
+%% Note:
+%% - Some servers (e.g. Microsoft-IIS/5.0) may sometimes not return a proper
+%% 'Location' header on a redirect.
+%% The client will fail with {error,no_scheme} in these cases.
