Apache gzip SOAP - apache

Question

I am new to Apache and I am trying to figure out how to enable gzip compression to send data over to clients (.NET Compact Framework devices).
I am using Apache 2.2 and so far, I have enabled mod_deflate.so but my content send over netwrok is not gzipped.
Any idea? much appreciated
UPDATE
I am on Windows using Apache 2.2. In my httpd.conf file, I uncommented this line.
LoadModule deflate_module modules/mod_deflate.so
My module Location is in httpd.conf file like this:
<Location /MyModule>
SetHandler mod_MyModule-handler
</Location>
And in httpd.conf file, I already had all this, so nothing was changed here except that I have uncommented DeflateCompressionLevel 9:
<Location />
# Insert filter
SetOutputFilter DEFLATE
# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/json
AddOutputFilterByType DEFLATE application/x-javascript
#DeflateCompressionLevel 9 //if I uncomment this, server wont start
# 1 to 9: 9 is the most compressed
# 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
#The following statement indicate which document types not to compress. Many type of documents do not compress well.
#At the end (Appendix 1) of this article some more type you might wish to also exclude from compression
# Don't compress images
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.(?:exe|t?gz|zip|bz2|sit|rar)$ no-gzip dont-vary
SetEnvIfNoCase Request_URI \.pdf$ no-gzip dont-vary
# Make sure proxies don't deliver the wrong content
# install/enable the Apache module mod_headers
Header append Vary User-Agent env=!dont-vary
# install/enable the Apache module LoadModule expires_module modules/mod_expires.so
# turn on the module for this directory
ExpiresActive on
# set defaults
ExpiresByType text/javascript "modification plus 11 months"
ExpiresByType application/javascript "modification plus 11 months"
ExpiresByType text/css "modification plus 11 months"
</Location>
Then I restart Apache, send request to it and receive response but response.ContentEncoding does not show "gzip" in .NETCF client. It looks like I am missing something.

uncomment the deflate module
LoadModule deflate_module modules/mod_deflate.so
and add this stanza to the virts config like this (be sure to include your soap mime type)
<IfModule deflate_module>
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
</IfModule>
bash test
function check_compression {
curl -s -k -I -H 'Accept-Encoding: gzip,deflate' $1 |grep "Content-Encoding"
}
check_compression http://your.url.com
If that doesn't work, check that you have the mime type set correctly for the soap response.
