Your should write your code as an input filter then, not a response handler.
Sorry, I was not quite clear in what I meant by "modifying the request".
I meant modifying stuff like the incoming HTTP headers or the URI, not
the content.
From what I understand of the documentation, by the time we get to the
input filter, we are already at the Response stage, which means all the
stuff about interpreting the headers, and assigning the request to
mod_jk, is already done. No ?
I get the impression that the input filter, contrary to handlers, is a
kind of "pull" module : it is invoked when (in this case) mod_jk reads
the request content, and gets to see (and possibly modify) the input
stream (buckets) of mod_jk on-the-fly.
Can an input filter then still modify the request, in the sense for
example of changing the request URI or adding/modifying incoming request
HTTP headers, or is it then too late for that ?
But assuming it can, there is another area which is still not clear to
me. I realise that this is not a specifically mod_perl question, but
would anyone happen to know ?
The mod_jk "re-direction" is specified in httpd.conf by the following
kind of config lines :
<IfModule mod_jk.c>
JkMount /xyz ajp13
JkMount /xyz/* ajp13
</IfModule>
That seems like a "server-level" specification, outside of any
<Location> or <Directory> section. On the other hand, a
PerlInputFilterHandler is a Directory-level specification. How would I
specify a mod_perl input filter for those same URI's ?
I don't know how to express this more clearly. I guess it would be
clearer if the mod_jk directives were expressed as
<Location /xyz>
JkMount ajp13
</Location>
and I could just insert the PerlInputFilterHandler in that same section,
but that's not how the mod_jk documentation says to do it.
