This was a key reason for my mod_dir patch that broke Brian's request, below. This is also a mod_negotiation bug, we simply hadn't realized it yet.

We are evidently not moving enough info from the subreq to the parent request in ap_fast_internal_redirect(); at least the filter chain, and some meta data related to the expires date.... Set{Input|Output}Filter[ByType] all set up filters in the typemap hook. It appears we did not copy these from the internal DefaultIndex subrequest back into the main request - we needed to. I'm not certain where the expires date is cached; the output headers? In any case, perhaps the entire headers need to slide from the sub request to the main request. A better answer is possibly to drop ap_internal_fast_redirect altogether (and changing both mod_dir and mod_negotiation to never use the beast again) - that includes Apache 1.3. This code, while normalized, is not much better than it was playing 1.3 negotiation. The code has been a source of vulnerabilities which I fixed, and other 'bugs' - most of which I'd fixed. Who knows how many more lurk, waiting to be 'discovered'. Axe ap_internal_fast_redirect()? Are any 3rd party modules taking advantage of this hack from negotiation? Bill
