sending CGI ouput through a handler

[Allen Day <al...@ucla.edu>]

Okay, I realize this has probably been covered before, but I couldn't find
anything in the archive...

I have a configuration like this:

<Location />
  SetHandler perl-script
  PerlHandler My::Handler
</Location>

My::Handler takes the requested file and adds some markup to it with the
Template Toolkit if the MIMEtype of the file is text/html.  I want to be
able to use the same handler to also add markup to the output of executed
CGI.  What is the best way to do this?

Should I set up a separate location for the CGI (I'm doing this,
actually) ?  Are there any extra directives needed?

TIA
Allen

You can't feed the output of mod_cgi to mod_perl, at least not in Apache
1.x.  The best thing to do (at least for performance) would be to
rewrite the CGI so that you call it as a module from your handler.
Another approach would be to use Apache::Filter to grab the output from
PerlRun or Regsistry.  You could also sublass PerlRun or Registry and
add your handler code to it.

by CGI do you mean a script running under mod_cgi? If it's registry you 
should be able to use stacked handlers:
