Description
Using mod_compress, when a page is sent gzipped, the Last-Modified and Etag headers are suppressed. This has the unfortunate effect that these pages can not be cached by a browser -- the browser lacks the required data to send If-Modified-Since and/or If-None-Match header(s) back.
Basically, as it is, you have to pick between cacheability or compression.
To reproduce, turn on compression and then make an HTTP request for a compressed page including the HTTP header "Accept-Encoding: gzip,deflate".

It can also suppreses the headers produced by mod_expire.

For some reason, this is the behavior when you don't turn on compress.cache-dir. Set this to a valid server path and Etag info is sent with mod_compress.

See http://trac.lighttpd.net/trac/ticket/1400 for an example of when this work-around will fail.
