I have tried using the following code but my website is still compressed using gzip:
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.(html?|txt|css|js|php|pl)$$ no-gzip dont-vary
How can I disable gzip compressions?
Put this code in the htaccess file and save it.It worked for me.Disabled gzip compression.
RewriteRule ^(.*)$ $1 [NS,E=no-gzip:1,E=dont-vary:1]
Thanks

Note
Someone suggested that this is a duplicate of How to serve precompressed gzip/brotli files with .htaccess. That question seeks only to serve pre-compressed files. This question is different. Please see below.
My Goal
I want to serve pre-compressed brotli files when they exist. If no pre-compressed brotli file exists, fall back to on-the-fly gzip-compression.
Current Code
I'm working on a site that already has on-the-fly gzip enabled from its .htaccess file as follows:
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml...
</ifmodule>
Modified Code
I've setup a build script that compresses many static assets with brotli. In order to serve them, I've replaced the above mod_deflate block with the following:
<IfModule mod_headers.c>
# Serve brotli compressed CSS and JS files if they exist
# and the client accepts brotli.
RewriteCond "%{HTTP:Accept-encoding}" "br"
RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
RewriteRule "^(.*)\.(js|css)" "$1\.$2\.br" [QSA]
# Serve correct content types, and prevent double compression.
RewriteRule "\.css\.br$" "-" [T=text/css,E=no-brotli:1]
RewriteRule "\.js\.br$" "-" [T=text/javascript,E=no-brotli:1]
<FilesMatch "(\.js\.br|\.css\.br)$">
# Serve correct encoding type.
Header append Content-Encoding br
# Force proxies to cache brotli &
# non-brotli css/js files separately.
Header append Vary Accept-Encoding
</FilesMatch>
</IfModule>
The Problem
This serves brotli-encoded files when they exist as expected. However, the problem I face now is that, because the remaining assets are not brotli-encoded at build time, they are now served with no compression.
I've been unable to figure out how I might serve brotli with a gzip fallback that does not require me to pre-compress for gzip output.
Any help is appreciated, thank you!
Your problem is you’ve replaced the dynamic gzip config with the static.
You need both bits of config in place but also to change your Brotli code to set the environment to no-gzip so it won’t fallback. The below should work;
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml...
</ifmodule>
<IfModule mod_headers.c>
# Serve brotli compressed CSS and JS files if they exist
# and the client accepts brotli.
RewriteCond "%{HTTP:Accept-encoding}" "br"
RewriteCond "%{REQUEST_FILENAME}\.br" "-s"
RewriteRule "^(.*)\.(js|css)" "$1\.$2\.br" [QSA]
# Serve correct content types, and prevent double compression.
RewriteRule "\.css\.br$" "-" [T=text/css,E=no-gzip:1]
RewriteRule "\.js\.br$" "-" [T=text/javascript,E=no-gzip:1]
<FilesMatch "(\.js\.br|\.css\.br)$">
# Serve correct encoding type.
Header append Content-Encoding br
# Force proxies to cache brotli &
# non-brotli css/js files separately.
Header append Vary Accept-Encoding
</FilesMatch>
</IfModule>
Im trying to serve precompressed gzip/brotli files for html, js and css.
With the following code.
RewriteEngine on
# Brotli
# If the web browser accept brotli encoding…
RewriteCond %{HTTP:Accept-encoding} br
# …and the web browser is fetching a probably pre-compressed file…
RewriteCond %{REQUEST_URI} .*\.(css|html|js)
# …and a matching pre-compressed file exists…
RewriteCond %{REQUEST_FILENAME}.br -s
# …then rewrite the request to deliver the brotli file
RewriteRule ^(.+) $1.br
# For each file format set the correct mime type (otherwise brotli mime type is returned) and prevent Apache for recompressing the files
RewriteRule "\.css\.br$" "-" [T=text/css,E=no-brotli,E=no-gzip]
RewriteRule "\.html\.br$" "-" [T=text/html,E=no-brotli,E=no-gzip]
RewriteRule "\.js\.br$" "-" [T=application/javascript,E=no-brotli,E=no-gzip]
# Gzip
# If the web browser accept gzip encoding…
RewriteCond %{HTTP:Accept-Encoding} gzip
# …and the web browser is fetching a probably pre-compressed file…
RewriteCond %{REQUEST_URI} .*\.(css|html|js)
# …and a matching pre-compressed file exists…
RewriteCond %{REQUEST_FILENAME}.gz -s
# …then rewrite the request to deliver the gzip file
RewriteRule ^(.+) $1.gz
# For each file format set the correct mime type (otherwise gzip mime type is returned) and prevent Apache for recompressing the files
RewriteRule "\.css\.gz$" "-" [T=text/css,E=no-brotli,E=no-gzip]
RewriteRule "\.html\.gz$" "-" [T=text/html,E=no-brotli,E=no-gzip]
RewriteRule "\.js\.gz$" "-" [T=application/javascript,E=no-brotli,E=no-gzip]
<FilesMatch "\.(css|html|js)\.br$">
# Prevent mime module to set brazilian language header (because the file ends with .br)
RemoveLanguage .br
# Set the correct encoding type
Header set Content-Encoding br
# Force proxies to cache brotli & non-brotli files separately
Header append Vary Accept-Encoding
</FilesMatch>
<FilesMatch "\.(css|html|js)\.gz$">
# Serve correct encoding type
Header set Content-Encoding gzip
# Force proxies to cache gzip & non-gzip files separately
Header append Vary Accept-Encoding
</FilesMatch>
My Folderstructure looks like this:
.htaccess
index.php
/css/
/css/main.css
/css/main.css.gz
/css/main.css.br
But I get 404s when using the code above.
Setting the RewriteBase fixed it.
RewriteBase /
Writing this to help others. I had to add %{DOCUMENT_ROOT} in the RewriteCond to get it to work.
Essentially, change all RewriteCond to
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME}\.br -s
For me the problem was, that brotli compression is not supported for http connections. See Why is Brotli not supported on HTTP?
I want to disable GZip for certain pages. I have this in my .htaccess, but it still turns GZip on (Content-Encoding: gzip) when visiting dashboard/index.
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI /dashboard/index no-gzip dont-vary
I tried to add Header set MyHeader %{REQUEST_URI} to see what the Request_URI was, but it gave an Internal Server Error.
I also tried the regex dashboard/index, dashboard/index.*, "/dashboard/index", etc., and tried SetEnvIfNoCase REQUEST_URI ..., but GZip was still on.
If I comment #AddOutputFilterByType, then GZip is turned off.
I'm using Apache 2.4.16, Yii 2.0.7, PHP. I'm using FPM in production, so apache_setenv() is not available.
You're probably using rewrites to get rid of index.php in the URL. Due to the stage at which SetEnvIf runs during the request, index.php will be part of the Request_URI var used (which is distinct from %{REQUEST_URI}).
It's nowadays quite common to not use PATH_INFO for rewrites, but just plainly rewrite to index.php, where code just reads the original REQUEST_URI info. In that case, Request_URI in SetEnvIf will be just "index.php", so you'd need to set a flag env var in a special dummy rewrite for that URL, and reference it later with a REDIRECT_ prefix (as there is an internal redirect stage on rewrites where mod_rewrite prefixes all existing env vars with REDIRECT_):
RewriteRule ^dashboard/index - [E=no-gzip:1]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . index.php [L]
SetEnvIf REDIRECT_no-gzip 1 no-gzip
There is a slightly less verbose way if you rewrite to PATH_INFO (so "/foobar" turns to "/index.php/foobar" using e.g. a RewriteRule (.*) index.php/$1 rule):
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule (.*) index.php/$1 [L]
SetEnvIfNoCase REQUEST_URI ^/index.php/dashboard/index.*$ no-gzip dont-vary
But that seems more brittle since it'll break if you change the RewriteRule mechanics.
I would like to disable gzip compression for some media files which are already compressed on an Apache server via the .htaccess file.
Reason: as it's written on e.g. jPlayer's site, gzip encoding should be disabled for media files: "Media files are already compressed and the GZIP will just waste CPU on your server. The Adobe Flash Plugin will experience issues if you GZIP the media."
I'm currently having the problem that Content-Length header is not properly set when gzip is enabled - so when playing some mp3-files with a SoundManager2 player, the track's length progress bar doesn't work appropriately (so maybe that's the problem they told about on jPlayer's site).
I can test if a content is served gzipped here.
I do have mod_deflate, mod_mime and mod_rewrite modules enabled on the server.
According to a phpinfo(), here is a list of all the loaded modules:
core mod_log_config mod_logio itk http_core mod_so mod_alias mod_auth_basic mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_autoindex mod_cgi mod_dav mod_dav_svn mod_authz_svn mod_deflate mod_dir mod_env mod_mime mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_ssl mod_status
I'm using Drupal 6, so I already have a RewriteRule, which is the following:
# Rewrite URLs of the form 'x' to the form 'index.php?q=x'.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !=/favicon.ico
RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]
I've already tried these to disable gzip, but they didn't work (there are 6 different tries! - maybe some of them would have to be set globally in Apache's httpd.conf?!):
# http://www.cyberciti.biz/tips/speed-up-apache-20-web-access-or-downloads-with-mod_deflate.html

RewriteRule \.mp3$ - [NS,E=no-gzip:1,E=dont-vary:1]
RewriteRule ^((.*)\.mp3)$ $1.mp3 [NS,E=no-gzip:1,E=dont-vary:1]
The only one which works correctly, and disables gzip compression, BUT it is global:
RewriteRule ^(.*)$ $1 [NS,E=no-gzip:1,E=dont-vary:1]
Response headers for an mp3-file when NOT using this RewriteRule: http://pastebin.com/AkUZ6m5Y
Response headers for an mp3-file when using this RewriteRule: http://pastebin.com/b8j3NF6D
I had to disable compression for odp files for use by external plugin
Just added the following rule in .htaccess file
SetOutputFilter DEFLATE
SetEnvIfNoCase Request_URI \.odp$ no-gzip dont-vary
And the server disabled compression for odp files
Make sure to clear the browser cache before testing
Are you not going about this the wrong way round by using the directive SetOutputFilter DEFLATE and then trying to disable this for stream which already include some form of compresstion? Isn't it a lot easier not to use this directive and then compress the stream that are compressible. E.g.
<IfModule mod_deflate.c>
AddOutputFilterByType DEFLATE text/html text/plain text/xml text/css application/x-javascript application/javascript application/ecmascript application/rss+xml
</IfModule>
And possibly adding a Vary header:
<IfModule mod_headers.c>
<FilesMatch "\.(js|css|xml|html)$">
Header append Vary Accept-Encoding
</FilesMatch>
</IfModule>
OK this may miss the odd type that you've not thought of, but it will achieve 99+% of your compression potential.
To disable gzip compression on just Adobe Flash Player files (SWFs) on my Apache server, I added this to my .htaccess file:
<IfModule mod_headers.c>
<FilesMatch "\.swf$">
RewriteRule ^(.*)$ $1 [NS,E=no-gzip:1,E=dont-vary:1]
</FilesMatch>
</IfModule>
If you wanted to, you could disable gzip compression for other file types as well:
<IfModule mod_headers.c>
<FilesMatch "\.(js|css|swf)$">
RewriteRule ^(.*)$ $1 [NS,E=no-gzip:1,E=dont-vary:1]
</FilesMatch>
</IfModule>
I think you are not using compression in your media. Did you check that you are in fact deflating files? The module can be loaded in memory, but that doesn't mean it's compressing files. If your .htaccess only has rewrite rules chances are you are not compressing any kind of content.
this seems outdated : https://www.varnish-cache.org/docs/3.0/tutorial/compression.html#gzip-and-esi
GZIP and ESI
If you are using Edge Side Includes you'll be happy to note that ESI
and GZIP work together really well. Varnish will magically decompress
the content to do the ESI-processing, then recompress it for efficient
storage and delivery.
I know this thread is old, but I have gone through the same path.
Two things I have done.
I enabled .htaccess and disabled gzip for a folder completely.
<Files "*.gz.asc">
RemoveEncoding .gz
</Files>
put a reqwrite rule to disable
RewriteRule "\.js\.gz$" "-" [T=text/javascript,E=no-gzip:1]
Both of these worked for me I would suggest going to Apache documentation first before searching on forums.
for more information please go to Apache website.
https://httpd.apache.org/docs/2.4/mod/mod_deflate.html
https://httpd.apache.org/docs/2.4/mod/mod_mime.html#addtype
Here's a list of stuff I tried in random order:
AddHandler application/x-httpd-php .otf
AddType
default_mimetype
auto_prepend_file = "otf.php"
zlib.output_compression = On
output_handler = ob_gzhandler
header("Content-type: application/octet-stream");
Even though all the PHP files of the server get gzipped using zlib, replacing the .otf extension by .php didn't work either.
With .htaccess, you could do like this, assuming font file is fontfile.otf.gz, browser request that as fontfile.otf
RewriteEngine On
#Check for browser's Accept-Encoding, remove it for force return gzipped one
RewriteCond "%{HTTP:Accept-Encoding}" "gzip.*deflate|deflate.*gzip"
#check file name is endswith otf
RewriteCond %{REQUEST_FILENAME} "\.(otf)$"
#check existance of .gz file name
RewriteCond %{REQUEST_FILENAME}.gz -s
#rewrite it to .otf.gz
RewriteRule ^.*$ %{REQUEST_URI}.gz [L]
#update some response header
<FilesMatch "\.otf\.gz$">
AddEncoding gzip .gz
ForceType "text/plain"
</FilesMatch>
And if font file and web site is cross-domain, you need to put Access-Control-Allow-Origin, firefox will not load font objects cross-domain.
In Gecko, web fonts are subject to the
same domain restriction (font files
must be on the same domain as the page
using them), unless HTTP access
controls are used to relax this
restriction.
Header set Access-Control-Allow-Origin *
