In ISPmanager you can configure compression of a website static content which includes files that can be easily modified (images, music, video, etc.). As a rule, such files consume much space and slow down your website. To compress them open the WWW-domain edit form and enable the option Compression and set a Compression level. Learn more under the article Add a WWW-domain. The maximum compression level is 9. The minimum is 1. We recommend setting 5.
The ngx_http_gzip_module module is a filter that compresses a request with gzip, enabling to reduce data size. If the compression is enabled, the following information is added into the Nginx configuration file for the WWW-domain:
Nginx configuration file
gzip on;
gzip_comp_level <compression level>;
gzip_disable "msie6";
gzip_types text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript
Perform the following steps to modify a list of data types:
ISPmanager configuration file
path nginx-gzip-types <data type>
E.g.: ISPmanager configuration file
path nginx-gzip-types text/plain text/css
/usr/local/mgr5/sbin/mgrctl -m ispmgr exit
