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.

156=item cookie_jar => $hash_ref
157
158Passing this parameter enables (simplified) cookie-processing, loosely
159based on the original netscape specification.
160
161The C<$hash_ref> must be an (initially empty) hash reference which will
162get updated automatically. It is possible to save the cookie_jar to
163persistent storage with something like JSON or Storable, but this is not
164recommended, as expire times are currently being ignored.
165
166Note that this cookie implementation is not of very high quality, nor
167meant to be complete. If you want complete cookie management you have to
168do that on your own. C<cookie_jar> is meant as a quick fix to get some
169cookie-using sites working. Cookies are a privacy disaster, do not use
170them unless required to.
