Varnish and mod_deflate support

[Jason Price]

First off, 3.0.7 is EOL.  Move to 4.x as soon as you can

Second, I'd leave the entire stanza out of VCL.  The varnish defaults
handle compression without issue in most cases.  If the backend serves
compressed data, it'll be cached as compressed, and served as compressed.

Third, once you 'pipe' a request, varnish does nothing other than packet
forwarding.  It can't cache, it can't balance requests across backends,
nothing.

If the above doesn't resolve your problem, try to capture a request Client
and Backend side transaction in varnishlog.  That will help diagnose what
the real problem is.
