App::HTTP_Proxy_IMP - HTTP proxy with the ability to inspect and modify content
# only use cmdline args App::HTTP_Proxy_IMP->new(@ARGV)->start; # only use given args App::HTTP_Proxy_IMP->new(\%options)->start; # combine cmdline args with given defaults App::HTTP_Proxy_IMP->new(\%options,@ARGV)->start; # short for App::HTTP_Proxy_IMP->new(...)->start; App::HTTP_Proxy_IMP->start(...); # show cmdline usage App::HTTP_Proxy_IMP->usage();
App::HTTP_Proxy_IMP implements an HTTP proxy, which can inspect and modify the HTTP header or content before forwarding. Inspection and modification is done with plugins implementing the Net::IMP interface.
The proxy is single-threaded and non-forking, but due to the event-driven model it can still process multiple connections in parallel. It is mainly intended to be used as a platform for easy prototyping of interesting ideas using IMP plugins, but should be also fast enough to be used to enhance, secure, restrict or protocol the browsing experience for small groups.
Creates a new object. The first argument might be an hash reference with options. All other arguments will be used as ARGV for cmdline parsing and might result in overwriting the defaults from OPTIONS.
The following options and its matching cmdline arguments are defined:
List of IMP filters, which should be used for inspection and modification. These can be a fully qualified name, or a short name, which need to be combined with one of the given namespace prefixes to get the full name. It can also be already an IMP factory object.
The cmdline option can be given multiple times. If '-' is given as name on the cmdline all previously defined filters are discarded.
The cmdline option can be given multiple times. If '-' is given at cmdline all previously defined prefixes (including defaults) are discarded.
Array of listener/upstream specifications for proxy. Each specification can be
On the cmdline these are given as the remaining arguments, e.g. after all other options.
The following options are only for the cmdline
Enable debugging. If RX is given it will be used as a regular expression to restrict debugging to given packages.
Outside the cmdline these settings can be done by setting
$DEBUG_RX exported by App::HTTP_Proxy_IMP::Debug.
Start the proxy, e.g. start listeners and process incoming connections. No arguments are expected if called on an object, but one can use the form
App::HTTP_Proxy_IMP->start(@args) as a shorter alternative to
If no return value is expected from this method it will enter into an endless loop using
AnyEvent->condvar->recv. If a value is expected it will return 1, and the caller hast to enter the AnyEvent mainloop itself.
The installs some signal handlers:
Dump current state to STDERR, e.g. active connections and their state.
Toggles debugging (e.g. enable|disable).
