mod-deflate

Imagine these two chunks of code residing in htaccess for speeding up the website. With php 5.2.3 on apache 2.0 block A # preserve bandwidth for PHP enabled servers <ifmodule mod_php4.c> php_value zlib.output_compression 16386 </ifmodule> block B # compress speficic filetypes <IfModule mod_deflate.c> <FilesMatch "\.(js|css|eot|ttf|svg|xml|ast|php)$"> SetOutputFilter DEFLATE </FilesMatch> </IfModule> Questions that arise: Q1. Is this the proper way to combine these two blocks A + B into 1 htaccess in the root? Q2. Is it correct that on the second block B, |php| is used again in the mod_edflate?

EDIT I have found that the problem is actually php minify . This was sending the deflated content instead of Apache. I'll find more on this. According to High Performance Web Sites , if I enable mod_deflate in Apache 2.x, by adding the following line, it should send gzipped/delfated content: - AddOutputFilterByType DEFLATE text/html text/css application/x-javascript The book also says that gzip is more effective than deflate . I have enabled in httpd.conf by adding the same line. But Apache sends Content-Encoding: deflate . I tested with CURL using: - curl -i -H "Accept-Encoding: gzip" "http:/

I'm using mod_deflate on Apache 2.2 and the compression level is set to 9. I've fine tuned every possible aspects of the site based on the recommendations of YSlow (v2) and have managed to get an overall A grade (Total Score: 91) as well as on all categories except for: Make fewer HTTP requests ( Grade C - I'm still working on further unification of images) Compress components with gzip ( Grade F ) YSlow still reports back with a F and tells me to use gzip on my CSS and JS files. Here's a screenshot of the YSlow report (the domain has been blurred out for the sake of privacy) : However, sites

I am trying to use the bigpipe concept on our website. That means trying to send the response in chunks instead of sending it as a whole so that user feels that page is fast. I am successful in doing that by using the flushBuffer method on the response object in java. But now when I try to compress the content with apache mod_deflate module, chunking is lost. Here is the configuration from apache used to compress the content ** Begin mod_deflate config DeflateBufferSize 100 AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript BrowserMatch ^Mozilla/4 gzip-only-text/html

Is there a command line command that can tell whether or not mod deflate is running on Apache? Juri Glass It is probably to late, but here we go. mod_deflate is enabled per default. To be sure, try debian / ubuntu: apache2ctl -t -D DUMP_MODULES CentOS: httpd -t -D DUMP_MODULES and look if there is a deflate_module. You can verify mod_deflate with this site: mod_deflate test My site gets a nice little report that shows I'm saving 81% of my bandwidth! You'll want to make sure the following line is present (and not commented out) in your apache configuration (httpd.conf): LoadModule deflate

I have a Liquid Web VPS account, I've made sure that mod_deflate is installed and running/active. I used to gzip my css and js files via PHP, as well as my PHP files themselves... However, I'm now trying to do this via mod_deflate, and it seems to work fine for all files except for PHP files. (Txt files work fine, css, js, static HTML files, just nothing that is generated via a PHP file.) How do I fix this? (I used the "Compress all content" option under "Optimize Website" in cPanel, which creates an .htaccess file in the home directory (not public_html, one level higher than that) with

I read some articles about HTTP headers compression. Today I installed YSlow and it recommends that I compress the resources (text/html, javascript, css and images). Now I'm reading the documentation for Apache mod_deflate but in the example don't compress images. Should I or should I not compress images in my site? Your images should already be compressed - any extra compression won't have any noticeable effect on filesize, but will increase processing time. .png files use DEFLATE compression already. .jpg files generally use lossy compression . .gif files use LZW compression .
