Compression and SSL are orthogonal - that is, they've nothing to do
with each other and shouldn't interfere. So it sounds like a spurious
correlation. What's really the problem is that you have two VHs, one of
which is configured correctly for compression and the other that isn't.
To test, switch off SSL in the SSL-VH (just comment out all SSL
directives and then connect via http on the same port, eg 443). Do you
still get compression?
To investigate, look at the request and response headers (eg, with
liveHTTPHeaders in Firefox). Do they make sense?
To fix, double-check the config; are you sure mod_deflate is configured
the same in both VHs? Also, check content and clients - remember that a
client can refuse to accept compressed content and that some contents
are never compressed (eg, JPG)..
If you don't fix it, post back some config snippets.
