To turn on Gzip compression, simply add on to the gzip directive in the main Nginx configuration file. $ sudo nano /etc/nginx/nginx. conf gzip on; Add file types to compress.
Double click on the file and select headers. Under 'Response headers' you are looking for the 'Connection-Encoding' field, it will say gzip if it is enabled.
Visit our webpage: https://smallseotools.com/check-gzip-compression/ Enter your Domain URL in the given field. Now press the “Check Compression” button.
Try this :
####################
# GZIP COMPRESSION #
####################
SetOutputFilter DEFLATE
AddOutputFilterByType DEFLATE text/html text/css text/plain text/xml application/x-javascript application/x-httpd-php
BrowserMatch ^Mozilla/4 gzip-only-text/html
BrowserMatch ^Mozilla/4\.0[678] no-gzip
BrowserMatch \bMSIE !no-gzip !gzip-only-text/html
BrowserMatch \bMSI[E] !no-gzip !gzip-only-text/html
SetEnvIfNoCase Request_URI \.(?:gif|jpe?g|png)$ no-gzip
It is better to implement it as in the snippet below.
Just paste the content below in your .htaccess
file, then, check the performance using: Google PageSpeed, Pingdom Tools and GTmetrics.
# Enable GZIP
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript

Your .htaccess should run just fine; it depends on four different Apache modules (one per each <IfModule>
directive). I guess one of the following:
your Apache server doesn't have either mod_filter, mod_deflate, mod_headers and/or mod_setenvif modules installed and running. If you can access the server config, please check /etc/apache2/httpd.conf
(and the related Apache config files); otherwise, you can see which modules are loaded via phpinfo()
, under the apache2handler section (see attached image); (EDIT) OR, you can open a terminal window and issue the command sudo apachectl -M
that will list the loaded modules;
if you get an http 500 internal server error, your server may not be allowed to use .htaccess files;
you are trying to load a PHP file that sends its own headers (overwriting Apache'sheaders), thus "confusing" the browser.
In any case, you should double-check your server config and error logs to see what's going wrong. Just to be sure, try to use the fastest way suggested here in Apache docs:
AddOutputFilterByType DEFLATE text/html text/plain text/xml
and then try to load a large textfile (preferably, clean your cache first).
(EDIT) If the needed modules are there (in the Apache modules dir) but aren't loaded, just edit /etc/apache2/httpd.conf and add a LoadModule directive for each one of them.
If the needed modules aren't there (neither loaded, nor in the Apache modules directory), I fear that the only option is reinstalling Apache (a complete version).
First of all go to apache/bin/conf/httpd.conf and make sure that mod_deflate.so is enabled.
Then go to the .htaccess file and add this line:
SetOutputFilter DEFLATE
This should output all the content served as gzipped, i have tried it and it works.
