 C<AnyEvent::HTTP::set_proxy>).
 Currently, if your proxy requires authorization, you have to specify an
 appropriate "Proxy-Authorization" header in every request.
+Note that this module will prefer an existing persistent connection,
+even if that connection was made using another proxy. If you need to
+ensure that a new connection is made in this case, you can either force
+C<persistent> to false or e.g. use the proxy address in your C<sessionid>.
 =item body => $string
 The request body, usually empty. Will be sent as-is (future versions of
 this module might offer more options).
 The default for this option is C<low>, which could be interpreted as "give
 me the page, no matter what".
 See also the C<sessionid> parameter.

 =item on_prepare => $callback->($fh)
 In rare cases you need to "tune" the socket before it is used to
 connect (for example, to bind it on a given IP address). This parameter
 In even rarer cases you want total control over how AnyEvent::HTTP
 establishes connections. Normally it uses L<AnyEvent::Socket::tcp_connect>
 to do this, but you can provide your own C<tcp_connect> function -
 obviously, it has to follow the same calling conventions, except that it
 may always return a connection guard object.
+The connections made by this hook will be treated as equivalent to
+connections made the built-in way, specifically, they will be put into
+and taken from the persistent connection cache. If your C<$tcp_connect>
+function is incompatible with this kind of re-use, consider switching off
+C<persistent> connections and/or providing a C<sessionid> identifier.
 There are probably lots of weird uses for this function, starting from
 tracing the hosts C<http_request> actually tries to connect, to (inexact
 but fast) host => IP address caching or even socks protocol support.
 =item persistent => $boolean
 Try to create/reuse a persistent connection. When this flag is set
 (default: true for idempotent requests, false for all others), then
 C<http_request> tries to re-use an existing (previously-created)
-persistent connection to the host and, failing that, tries to create a new
+persistent connection to same host (i.e. identical URL scheme, hostname,
-one.
+port and sessionid) and, failing that, tries to create a new one.
 Requests failing in certain ways will be automatically retried once, which
 is dangerous for non-idempotent requests, which is why it defaults to off
 for them. The reason for this is because the bozos who designed HTTP/1.1
 made it impossible to distinguish between a fatal error and a normal
 connection timeout, so you never know whether there was a problem with
 your request or not.
 When reusing an existent connection, many parameters (such as TLS context)
-will be ignored. See the C<session> parameter for a workaround.
+will be ignored. See the C<sessionid> parameter for a workaround.
 =item keepalive => $boolean
 Only used when C<persistent> is also true. This parameter decides whether
 C<http_request> tries to handshake a HTTP/1.0-style keep-alive connection

 A cookie jar is initially an empty hash-reference that is managed by this
 module. Its format is subject to change, but currently it is as follows:
-The key C<version> has to contain C<1>, otherwise the hash gets
+The key C<version> has to contain C<2>, otherwise the hash gets
-emptied. All other keys are hostnames or IP addresses pointing to
+cleared. All other keys are hostnames or IP addresses pointing to
 hash-references. The key for these inner hash references is the
 server path for which this cookie is meant, and the values are again
 hash-references. Each key of those hash-references is a cookie name, and
 the value, you guessed it, is another hash-reference, this time with the
 key-value pairs from the cookie, except for C<expires> and C<max-age>,
 Here is an example of a cookie jar with a single cookie, so you have a
 chance of understanding the above paragraph:
