11This module is an L<AnyEvent> user, you need to make sure that you use and 15This module is an L<AnyEvent> user, you need to make sure that you use and
12run a supported event loop. 16run a supported event loop.
17
18This module implements a simple, stateless and non-blocking HTTP
19client. It supports GET, POST and other request methods, cookies and more,
20all on a very low level. It can follow redirects supports proxies and
21automatically limits the number of connections to the values specified in
22the RFC.
23
24It should generally be a "good client" that is enough for most HTTP
25tasks. Simple tasks should be simple, but complex tasks should still be
26possible as the user retains control over request and response headers.
27
28The caller is responsible for authentication management, cookies (if
29the simplistic implementation in this module doesn't suffice), referer
30and other high-level protocol details for which this module offers only
31limited support.

58must be an absolute http or https URL. 91must be an absolute http or https URL.
59 92
93The callback will be called with the response data as first argument
94(or C<undef> if it wasn't available due to errors), and a hash-ref with
95response headers as second argument.
96
97All the headers in that hash are lowercased. In addition to the response
98headers, the three "pseudo-headers" C<HTTPVersion>, C<Status> and
99C<Reason> contain the three parts of the HTTP Status-Line of the same
100name. If the server sends a header multiple lines, then their contents
101will be joined together with C<\x00>.
102
103If an internal error occurs, such as not being able to resolve a hostname,
104then C<$data> will be C<undef>, C<< $headers->{Status} >> will be C<599>
105and the C<Reason> pseudo-header will contain an error message.
106
107A typical callback might look like this:
108
109 sub {
110 my ($body, $hdr) = @_;
111
112 if ($hdr->{Status} =~ /^2/) {
113 ... everything should be ok
114 } else {
115 print "error, $hdr->{Status} $hdr->{Reason}\n";

140=item proxy => [$host, $port[, $scheme]] or undef
141
142Use the given http proxy for all requests. If not specified, then the
143default proxy (as specified by C<$ENV{http_proxy}>) is used.
144
145C<$scheme> must be either missing or C<http> for HTTP, or C<https> for
146HTTPS.
147
148=item body => $string
149
150The request body, usually empty. Will be-sent as-is (future versions of
151this module might offer more options).
152
153=item cookie_jar => $hash_ref
154
155Passing this parameter enables (simplified) cookie-processing, loosely
156based on the original netscape specification.
157
158The C<$hash_ref> must be an (initially empty) hash reference which will
159get updated automatically. It is possible to save the cookie_jar to
160persistent storage with something like JSON or Storable, but this is not
161recommended, as expire times are currently being ignored.
162
163Note that this cookie implementation is not of very high quality, nor
164meant to be complete. If you want complete cookie management you have to
165do that on your own. C<cookie_jar> is meant as a quick fix to get some
166cookie-using sites working. Cookies are a privacy disaster, do not use
167them unless required to.
