11 | This module is an L<AnyEvent> user, you need to make sure that you use and |
12 | run a supported event loop. |
12 | run a supported event loop. |
|
|
13 | |
|
|
14 | This module implements a simple, stateless and non-blocking HTTP |
|
|
15 | client. It supports GET, POST and other request methods, cookies and more, |
|
|
16 | all on a very low level. It can follow redirects supports proxies and |
|
|
17 | automatically limits the number of connections to the values specified in |
|
|
18 | the RFC. |
|
|
19 | |
|
|
20 | It should generally be a "good client" that is enough for most HTTP |
|
|
21 | tasks. Simple tasks should be simple, but complex tasks should still be |
|
|
22 | possible as the user retains control over request and response headers. |
|
|
23 | |
|
|
24 | The caller is responsible for authentication management, cookies (if |
|
|
25 | the simplistic implementation in this module doesn't suffice), referer |
|
|
26 | and other high-level protocol details for which this module offers only |
|
|
27 | limited support. |

149 | =item cookie_jar => $hash_ref |
|
|
150 | |
|
|
151 | Passing this parameter enables (simplified) cookie-processing, loosely |
|
|
152 | based on the original netscape specification. |
|
|
153 | |
|
|
154 | The C<$hash_ref> must be an (initially empty) hash reference which will |
|
|
155 | get updated automatically. It is possible to save the cookie_jar to |
|
|
156 | persistent storage with something like JSON or Storable, but this is not |
|
|
157 | recommended, as expire times are currently being ignored. |
|
|
158 | |
|
|
159 | Note that this cookie implementation is not of very high quality, nor |
|
|
160 | meant to be complete. If you want complete cookie management you have to |
|
|
161 | do that on your own. C<cookie_jar> is meant as a quick fix to get some |
|
|
162 | cookie-using sites working. Cookies are a privacy disaster, do not use |
|
|
163 | them unless required to. |
