Description Edgar Ehritt 2009-05-22 13:56:26 UTC
https://issues.apache.org/bugzilla/show_bug.cgi?id=39727 is past, but it
would seem Apache do not understand its own new generated values with suffix
"-gzip" of Etag received in If-None-Match header. Each resource at each
request is compressed on-the-fly. Status 304 respose does not occur.

Example configuration: =====================================================

<FilesMatch "\.(css|...)$">
	SetOutputFilter	DEFLATE

HTTP request and response: =================================================

GET /manual/style/css/manual.css HTTP/1.1
Host: server.tld
User-Agent: Firefox/3.0
Accept: text/css,*/*;q=0.1
Accept-Language: de,de-de;q=0.8,en;q=0.5,en-us;q=0.3

Content-Encoding: gzip

Identically there are values of If-Modified-Since and If-None-Match as well as Last-Modified and Etag.
Comment 1 Ruediger Pluem 2009-05-23 01:37:04 UTC
This will be fixed in the next 2.2.x release due to r761835.
