[users@httpd] problem when using mod_deflate and zip files and IE6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi there,

When I use the following combination:

Apache 2.049
Linux (SuSe 9.1)
mod_deflate

and a zip file is served to a IE6 client, the file can not be used anymore. (I get an error by win zip claiming that it is not a valid zip archive)

I tried to suppress that mod_deflate by the following rule. This did help with *.pdf files (which had the same problem), but not zip files.

Any help would be greatly appreciated.

<IfModule mod_deflate.c>
DeflateCompressionLevel 3

DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio

LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' 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

# NOTE: Due to a bug in mod_setenvif up to Apache 2.0.48
# the above regex won't work. You can use the following
# workaround to get the desired effect:
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html

# Don't compress images, java scripts and style sheets
#_robert_ pdf, gz hinzugeuegt
SetEnvIfNoCase Request_URI \
  \.(?:gif|jpe?g|png|js|css|pdf|gz|zip)$ no-gzip dont-vary

# Make sure proxies don't deliver the wrong content
# this needs mod_headers but it's very important
# so I don't add a IfModule around it
Header append Vary User-Agent env=!dont-vary

</IfModule>
