[users@httpd] 304 Not Modified and deflate OutputFilter
The deflate filter seems to break Apache's handling of the 304 Not
Modified status.
Apache package: apache2-mpm-prefork 2.2.8-1ubuntu0
In the Apache config, if I load mod_deflate and include:
AddOutputFilterByType DEFLATE text/plain
Request /test.txt so the browser caches it, then request it again:
------------------------------------------------------------------------
GET /test.txt HTTP/1.1

------------------------------------------------------------------------
FWICS the response could 304 on the basis of either the Etag or
Last-Modified. If I rename test.txt to some mime type that doesn't
have an associated outputfilter, the response 304s as expected.
Is this a bug? How do I make httpd return a 304 status in this
situation, while still gzipping content where applicable?

Correct.
This is a known issue that noone has found time to fix.
Patches welcome.
