mod_deflate recommended configuration
Hello.
I took the recommended configuration of
http://httpd.apache.org/docs-2.0/mod/mod_deflate.html but we encountered
an error with IE 5.5 and IE 6 browser, regarding this bug:
http://support.microsoft.com/default.aspx?scid=kb%3Ben-us%3B327286 .
As a result, we had to remove compression for .js and .css files, as set
in the mod_gzip configuration.
Here our actual mod_deflate configuration:
<Location />
# # Insert filter
SetOutputFilter DEFLATE
# # Netscape 4.x has some problems...
BrowserMatch ^Mozilla/4 gzip-only-text/html
# # Netscape 4.06-4.08 have some more problems
BrowserMatch ^Mozilla/4\.0[678] no-gzip
# # MSIE masquerades as Netscape, but it is fine
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
# # Don't compress images
SetEnvIfNoCase Request_URI \
\.(?:gif|jpe?g|png|js|css)$ no-gzip dont-vary
# # Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary
</Location>
Note the modification of SetEnvIfNoCase. The recommended configuration
could have a problematic behaviour. What is the correct thing to do to
suggest a modification?
Rgds.

Well. Rather difficult to say, but we have a client who can't see a page
(with ou without frame) on our site when we have js compression. We made
tests, and the problem seems to occur every 50 to ... times. Not very often.
MS says that the bug is only present on MSIE 6 whereas we have tested it
against a IE 5.5.
It's a bug on a MSIE version, and it seems that MS has not release a
patch to correct it. As MSIE6 and 5.5 represent nearly a very large part
of the browser (on our stats: 83%), the problem is real.

You're doing it now.
But from looking at the ms knowledge base article, it seems like this will
only occur in very rare circumstances involving frames and cache-control
headers. It would be a shame to never compress js/css to work around a
rare problem. Is this a more common problem than MS suggests?
