179=item tls_ctx => $scheme | $tls_ctx
180
181Specifies the AnyEvent::TLS context to be used for https connections. This
182parameter follows the same rules as the C<tls_ctx> parameter to
183L<AnyEvent::Handle>, but additionally, the two strings C<low> or
184C<high> can be specified, which give you a predefined low-security (no
185verification, highest compatibility) and high-security (CA and common-name
186verification) TLS context.
187
188The default for this option is C<low>, which could be interpreted as "give
189me the page, no matter what".
190
191=item on_header => $callback->($hdr)
192
193When specified, this callback will be called with the header hash as soon
194as headers have been successfully received from the remote server (not on
195locally-generated errors).
196
197It has to return either true (in which case AnyEvent::HTTP will continue),
198or false, in which case AnyEvent::HTTP will cancel the download (and call
199the finish callback with an error code of C<598>).
200
201This callback is useful, among other things, to quickly reject unwanted
202content, which, if it is supposed to be rare, can be faster than first
203doing a C<HEAD> request.
204
205=item on_body => $callback->($data, $hdr)
206
207When specified, all body data will be "filtered" through this callback.
208
209The callback will incrementally receive body data, and is supposed to
210return it or a modified version of it (empty strings are valid returns).
211
212If the callback returns C<undef>, then the request will be cancelled.
213
214This callback is useful when you want to do some processing on the data,
215or the data is too large to be held in memory (so the callback writes it
216to a file and returns the empty string) and so on.
217
218It is usually preferred over doing your own body handling via
219C<want_body_handle>.
220
221=item want_body_handle => $enable
222
223When enabled (default is disabled), the behaviour of AnyEvent::HTTP
224changes considerably: after parsing the headers, and instead of
225downloading the body (if any), the completion callback will be
226called. Instead of the C<$body> argument containing the body data, the
227callback will receive the L<AnyEvent::Handle> object associated with the
228connection. In error cases, C<undef> will be passed. When there is no body
229(e.g. status C<304>), the empty string will be passed.
230
231The handle object might or might not be in TLS mode, might be connected to
232a proxy, be a persistent connection etc., and configured in unspecified
233ways. The user is responsible for this handle (it will not be used by this
234module anymore).
235
236This is useful with some push-type services, where, after the initial
237headers, an interactive protocol is used (typical example would be the
238push-style twitter API which starts a JSON/XML stream).
239
240If you think you need this, first have a look at C<on_body>, to see if
241that doesn'T solve your problem in a better way.
