The filter inserts a header and a footer in the page from two files. I can

Is the filter your own, or supplied by a third-party?
If you have access to the source, please check whether it sets the
AP_FILTER_PROTO_NO_CACHE flag in ap_register_output_filter_protocol.
I created the filter myself so I changed the registration from
ap_register_output_filter("TESTFILTER", testfilter_filter, NULL,
AP_FTYPE_CONTENT_SET);
to
ap_register_output_filter("TESTFILTER", testfilter_filter, NULL,
AP_FTYPE_CONTENT_SET|AP_FILTER_PROTO_NO_CACHE);
This doesn't seem to change anything though. I still get the 304 response
without any headers that forbid caching.
Just out of interest shouldn't the FilterProtocol directive with cache=no
have the same effect as the flag and if I set the flag in the code can I
remove the directive from the configuration (once cache prevention is
working as intended)?
Ok, so I just noticed you were talking about
ap_register_output_filter_protocol() and not ap_register_output_filter() so
I guess the change above is pretty useless.
The question is how/where do I add the ap_register_output_filter_protocol()
call? Is that something I do in addition to the content filtering I do now
or does it replace what I'm currently doing i.e. do I turn my resource
filter into a protocol filter (which doesn't sound right)?
