I have a stateful HTTP parser module that I've mentioned on the module-authors list and it was suggested that it be incorporated into LWP rather than directly added to CPAN.
I'm aware of a couple of HTTP request parsers (e.g. in POE::Component::Server::HTTP, HTTP::Daemon, and probably in SOAP::Lite too) but not a standalone one. The module's add() method takes data and returns a 'hint' as to what it wants next (dies on error): 0 - done, call request() to get an HTTP::Request object >0 - want this many bytes (e.g. Content-Length or chunked encoding) -1 - need more data, not sure how much -2 - need (at least) a full line of data Of course, the hints can be completely ignored and data can just be passed in as received. The module itself is viewable (temporarily) at http://davidrobins.net/code/misc/HTTP-Parser.pm. I wrote it as part of an RVP (MS Instant Messenger) client, using the Event module for the event loop. -- Dave Isa. 40:31
