Hi.
The following is verbatim what I posted earlier on the Apache user's
list. I am reposting it here because I did not really get a
"satisfactory" answer on the Apache httpd list, and because I know that
mod_jk experts lurk around here. And maybe this has something to do with
the fact that the requests we're talking about are handled by a Tomcat
webapp, after being re-directed by Apache/mod_jk.
The underlying question is also : despite what I'm saying below about
not being able to change the webapp (which is basically true), I think I
should be able to change the Content-Type header (which I believe is
generated by the rogue webapp or by Tomcat itself), *before* it gets
sent back to Apache via mod_jk.
And I guess that in order to do that, I would have to create a servlet
filter that acts at the output level. How hard would that be to do ?
(I already have a servlet filter around this webapp, but at the moment
it only acts on the input side).
Original message to Apache list follows :
I am a bit at my wit's end here.
Using Apache 2.2.3 under Suse Linux, with a mod_jk re-director to Tomcat
(5.0.x) for certain links, such as the one of which question below.
I am using a Tomcat java application which unfortunately sets the
Content-Type response header wrongly : it says "text/html;
charset=iso-8859-1" instead of "text/html; charset=iso-8859-2", and
there is no way I can change that application itself.
So I am trying to rectify that header after-the-fact, using mod_headers.
Unfortunately, it does not seem to work.
I have this Vhost configuration (snippet) :
SetEnvIf REQUEST_URI "/servlet\.[^\.]+$" is-jk
Header always set Content-Type: "text/html; charset=ISO-8859-2" env=is-jk
Header always set Test-Header: "VHost level" env=is-jk
<LocationMatch "/servlet\.[^.]+$">
SetHandler jakarta-servlet
Header always set Content-Type: "text/html; charset=ISO-8859-2"
Header always set Test-Header: "Location level"
</LocationMatch>
I capture the HTTP headers resulting from a request, using the
LiveHttpHeaders plugin of Firefox, as follows (sorry for the email
wrap-around, and sensitive bits edited-out with XXX):
POST /starweb/XXX/servlet.starweb HTTP/1.1
Host: XXX.XXX.XXX

As can be seen above, the "Test-Header" that I set with mod_headers
comes out perfectly, from the Location section.
But the Content-Type header, which I believe should be set in the same
exact conditions, does not.
Does anyone have an idea why ?
Thanks.
