Greetings,
We are using Apache 2.0.52, 32-bit, and I have tried to enable
mod_deflate. It works for some content, but most notably, it does not
work for content that is directed via the Rewrite engine to a proxy
server.
I am separately logging all requests that do *not* have "no-gzip"
environment variable set. Filtering through this log for the
compression ratio, I can determine which URLs are and are not
deflated. Excluding favicons and flash files, quite a few files that
are being proxied do *not* get deflated. Why?
For instance, the following URL (prefixed with the mime/type) only
gets served through our proxies via a Java application server.
text/html
/at/guide/54949at,de,SCH1/ffs,2,objectId,RGN190at,curr,EUR,folder,EVENT,season,at2,selectedEntry,event/event.html
However, even some static content does not get deflated:
text/javascript /at/uptodate/static/5,de,SCH1/_/local.js
Some URLs that are proxied to a PHP server ARE deflated:
text/html
/xxl/_lang/de/_site/innsbruck/_area/453003/_subArea/463299/index.html
Is this a known issue with proxying? (CHANGE_LOGs of Apache helped me
none.) What headers might an application or proxy server generate that
would somehow disable mo_deflate WITHOUT generating the no-gzip
environment variable?
