The system uses ngx_http_gzip_module.

The ngx_http_gzip_module is a filter that compresses the response by the gzip method, which reduces the size of the transferred data by a factor of 2 or more

server {  
           gzip on;
           `` gzip_disable "msie6";
           gzip_types text/plain application/xml;
           gzip_comp_level 5;

Directives (the value next to the directive is set by default by the panel):

gzip on - Enables gzip compression of the response.

gzip_disable "msie6" - Disables gzip compression for requests with "User-Agent" header fields that match the specified regular expressions. The special mask "msie6" corresponds to the regular expression "MSIE [4-6].", but works faster.

gzip_types "text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript" - Enables gzip compression for specified MIME types in addition to "text/html". Replies with the "text/html" type are always compressed.

To change the list of MIME-types you need: in the configuration file /usr/local/mgr5/etc/ispmgr.conf, create a variable path type named nginx-gzip-types and enter the desired MIME-types. For example:

path nginx-gzip-types text/plain text/css  

If compression settings have already been made for the domain, applying the changes in gzip_types will require reloading the panel and then applying the changes to the WWW domain.

gzip_comp_level 1-9 - Sets the degree of gzip compression of the response. Valid values range from 1 to 9.

To enable GZIP compression it is necessary: in WWW-domain settings to enable the switch Configure compression, then select the compression level and save the form.
