How to enable compression in WAMP running on Windows Server 2008?

I searched the net and I followed these steps given here: http://www.zigpress.com/2009/04/09/enabling-gzip-on-wamp/.

But after restarting my WAMP the icon got yellow not green.

Than followed this post: http://forum.wampserver.com/read.php?2,93406.

Again the same problem my WAMP icon after restarting gets yellow.

This is the code I put in Apache httpd.conf:

<ifmodule mod_deflate.c>
 AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css text/javascript   application/x-javascript application/javascript

Did you try to use .htaccess instead of httpd.conf? – Zistoloen Oct 22 '13 at 7:29
If you have any example please share it – Mehdi Jalal Oct 22 '13 at 8:05

To enable Deflate compression for resources with WAMP (thus Apache), you can use this following code in your .htaccess file:

<IfModule mod_deflate.c>
<FilesMatch "\.(html|php|txt|xml|js|css)$">
SetOutputFilter DEFLATE

It works well for several websites I own.

Thanks very much it worked for me – Mehdi Jalal Oct 22 '13 at 10:03
You're welcome. – Zistoloen Oct 22 '13 at 10:47

For use, AddOutputFilterByType should also activate the filter module. Uncomment LoadModule filter_module modules/mod_filter.so in the httpd.conf file

+1 In the default WAMP installation, one can enable the deflate module from the UI, but this will not be enough if you want to use AddOutputFilterByType. You will also need to do this. – Odys Mar 21 '15 at 22:40
