Enable g-zip for IBM HTTP Server

Posted by eichelgartenweg on 2:45 PM with 1 comment
In order to deflate the content served form a IBM HTTP Server (IHS) it is possible to enable the g-zip-option in httpd.conf to compress the traffic between a client and a IHS.

To enable g-zip add this lines at the bottom of httpd.conf:

# compress everything but images
LoadModule deflate_module modules/mod_deflate.so
DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio
# log some info
#LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
#CustomLog logs/deflate_log deflate
# 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 \
\.(?:gifjpe?gpngexe)$ no-gzip dont-vary
