Subject [users@httpd] mod_deflate with ie6 with http/1.0 problems
Date Wed, 27 Feb 2008 07:36:15 GMT
Hello members,

I have found a problem, if apache (my version 2.0.59) with mod_deflate
enabled, and if requesting the objects by IE6 with HTTP/1.0 protocal,
the browser can't get the objects correctly.
The errors happened on only ie6 (or ie5,didn't test it) with http/1.0
enabled. It works fine on ie7 and firefox, and also works fine on ie6
with http/1.1 enabled.
The screencut for request and responce headers is here:

Also this is Apache's config for mod_deflate:

AddOutputFilterByType DEFLATE text/html text/plain text/xml  text/css

<Location /test>

# 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)$ no-gzip dont-vary

# Make sure proxies don't deliver the wrong content
Header append Vary User-Agent env=!dont-vary


Please tell me why this happened. Thanks.
