compression mod_deflate is not working on apache2

I have two websites on my apache server. I have already enabled mod headers and deflates. in /etc/apache2/mod-available/deflate.conf i have written:

<IfModule mod_deflate.c>

SetOutputFilter DEFLATE
DeflateCompressionLevel 9

AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4.0[678] no-gzip
BrowserMatch bMSIE !no-gzip !gzip-only-text/html

DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio

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

Header append Vary User-Agent env=!dont-vary


but each time i check my website through the different commpression test the result is always: Compression status: Uncompressed

i tried to insert the code in /etc/apache2/site-available/ but it doesnt work. Have i missed something? I would be really gratefull if anyone can help.

can you try adding in your v-host configuration, just for testing this:

<Location /tempFolder/>
        SetOutputFilter DEFLATE

restart apache and see if the responses get gziped - eg by:

wget --header "Accept-encoding: gzip"

if compression works - you should get file.txt that can be unpacked with gunzip.

maybe the mod_deflate is not loaded after all?
