I trying enable output compression for Apache 2.2.15, and 5.3.3, but web-pages generated by php is not compressing :(

My deflate.conf:

[user@host conf.d]# cat deflate.conf 
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE application/x-httpd-php
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

DeflateCompressionLevel 9

# Browser specific settings
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
BrowserMatch \bOpera !no-gzip 

# Setup custom deflate log
DeflateFilterNote Input instream
DeflateFilterNote Output outstream
DeflateFilterNote Ratio ratio
LogFormat '"%r" %{outstream}n/%{instream}n (%{ratio}n%%)' deflate
# Example of log file
CustomLog logs/deflate_log DEFLATE

And string in vhost config file for logging:

CustomLog logs/vhost/deflate_log deflate

And what I see in log:

This answer gives the best summary of issues that can pop up in Apache 2.2 with mod_deflate. The solution is to use filter_module & deflate_module instead:

# Declare a "gzip" filter, it should run after all internal filters like PHP or SSI
FilterDeclare  gzip CONTENT_SET

# "gzip" filter can change "Content-Length", can not be used with range requests
FilterProtocol gzip change=yes;byteranges=no

# Enable "gzip" filter if "Content-Type" contains "text/html", "text/css" etc.
FilterProvider gzip DEFLATE resp=Content-Type $text/html
FilterProvider gzip DEFLATE resp=Content-Type $text/css
FilterProvider gzip DEFLATE resp=Content-Type $text/javascript
FilterProvider gzip DEFLATE resp=Content-Type $application/javascript
FilterProvider gzip DEFLATE resp=Content-Type $application/x-javascript

# Add "gzip" filter to the chain of filters
FilterChain    gzip
