Jou could try to set a location handler for SetHandler perl-script PerlHandler My::HandleEverything your handler could tie the output-handle (is this possible?) and run a subrequest. Now it could intercept the output (written to the handle) and do changes, or tidy it up, whatever you want.. And at least, it should return DECLINE, if it isn't the main-request I'm not sure if this will work, because of the needed tie of the outputhandle and so on, maybe anyone else can give a better statement ;))) -- Mit freundlichen Grüßen - Nico Erfurth Headlight Housingfactory GmbH Email: [EMAIL PROTECTED] -
Re: Making perl handlers handle non-Perl
As far as I understand, it should be a chain of handlers. It's very close to
one of my current projects. You have to serve one of the early stages of the
request to decide what handler is appropriate for the content generation
phase in particular conditions, and dynamically install that handler, which
in fact should be a kind of content filter...

If you aren't terribly concerned about performance, there are several Apache::Proxy modules which should be easy to modify to put your lint checking in. Do a search for "proxy" on CPAN to see what's out there. - Perrin

You might try > using a proxy server setup to do this instead. ah, yes. right, you can't intercept the output of other content handlers, like mod_php or mod_cgi. you can get to stuff handled by mod_perl via Apache::Filter, or stuff that would be handled by core Apache by manipulating the resource on disk directly (using $r->filename), but that's about it. at least for 1.3 (though I've always been curious how mod_gzip works with 1.3) seems I had my brain in the wrong place - thanks Perrin. --Geoff

THAT'S the answer I was looking for. Not what I wnated, but at least it
answers my question. :-)
So, my HTML::Lint checking is only going to work on output from the
mod_perl chain. I guess that's better than nothing, but I've got plenty
of PHP code that I'd like to filter thru it as well.
Thanks, all.

Or PHP for > that matter? oh, no. if you want to intercept absolutely _everything_ I suspect that SetHandler perl-script at the server level will do the trick (outside of any or other container directive). just make sure you have a PerlHandler My::Foo somewhere to fill in the mod_perl part, since mod_perl needs both directives to work. typically, folks don't want to intercept all requests - it's generally better to let Apache serve static files itself so that it handles stuff like HTTP/1.1 conditional headers and the like. > > I want my MyFilter to process EVERYTHING that Apache spits out, whether > with mod_perl, mod_php or just reading a .html file from the filesystem, > especially the mod_php stuff. > > Should I be looking at one of the later phases (cleanup?) instead of > content generation? the content-generation phase should be fine.

So what we're saying is that with static .html files, there's no way for
me to get mod_perl to interject itself into Apache's chain? Or PHP for
that matter?
I want my MyFilter to process EVERYTHING that Apache spits out, whether
with mod_perl, mod_php or just reading a .html file from the filesystem,
especially the mod_php stuff.
Should I be looking at one of the later phases (cleanup?) instead of
content generation?
Thanks,
Andy

Making perl handlers handle non-Perl
How can I get mod_perl to handle all Apache output, whether or not it
originates with mod_perl?
I'm writing a module that needs to analyze all output generated by Apache.
That's easy enough with stacked handlers, but I'm goofing something up
with, say, static HTML.
If I do this:
PerlHandler MyFilter
Then static HTML gets served up OK, but MyFilter doesn't seem to get
called. Or is it, and I'm screwing something up in the filter?
And of course if I do this:
SetHandler perl-script
PerlHandler MyFilter
Then I get no output because the .html files that I'm trying to serve up
out of /test aren't Perl.
Pointers please? I've got both the Cookbook and the Eagle book if you
want to just point to a page.
Thanks,
Andy
