Apache 2 and mod_ocaml

Apache 2 and mod_ocaml

[Joe Polanik]

Is there a version of mod_ocaml for Apache 2? If so, where might this be 
found?

Thanks,

Joe

mod_caml or mod_ocaml?  The two are different things.  My summary of
the situation is here:

http://caml.inria.fr/archives/200410/msg00026.html

You need to patch Apache 2 to run mod_caml.  See these instructions:

http://merjis.com/developers/mod_caml/apache_2.0
http://issues.apache.org/bugzilla/show_bug.cgi?id=27550

The process of getting the required patch into Apache 2.x is glacial,
but at least the developers are now showing some small amount of
interest.

Has anyone looked at getting mod_lisp to work with OCaml? It's different from 
mod_caml in that it doesn't execute OCaml code in Apache itself, but connects 
to a separate process, which handles the request. Much like the way in which 
Java servlet support for Apache works. It doesn't transfer any LISP specific 
stuff according to the docs.

There is support for AJP (the Java connector you mention) and FastCGI in
Ocamlnet (http://ocamlnet.sourceforge.net). The O'Caml code runs in a
separate process, with all advantages, e.g. native code support, increased
stability etc.

The trouble is that FastCGI seems to be no longer actively developed, 
and it hardly supports Apache2.

Oacmlnet supports JServ too, IIRC.

Gerd has managed to write in Ocaml every possible computable function, 
so, yes, he does support Jserv. Again, the problem is elsewhere. The 
Jakarta project no longer supports the Jserv protocol version 
implemented by Gerd. Gerd is not updating the Jserv support, if I recall 
correctly, because the new protocol version lacks support for some of 
the CGI features Ocamlnet needs.

According to the documentation, mod_lisp uses a simpler protocol than JServ. 
It consists of attributename/value pairs.

I never really understood why people don't just use HTTP.  It is,
after all, a perfectly suitable protocol for transfering web requests
and web pages between entities :-)

This is what we are doing with the xcamld. Xcamld is a light-weigh http 
server working behind the scenes of a full-fledged server like Apache, 
which has support for proxying a request to another server. The client 
connects to Apache via HTTP; Apache is configured to act as a 
transparent proxy for this request and relays it to the xcamld. We 
already have a complete implementation of the HTTP 1.1 protocol and are 
currently working on the Ocamlnet bindings.

Well, the other protocols are simpler than HTTP and therefore cost less effort 
to implement.
