.htaccess Map extensions to media types
Map extensions to media types
Map the following filename extensions to the specified encoding type using AddEncoding so Apache can serve the file types with the appropriate Content-Encoding
response header.
note
This will not make Apache compress them!
If these files types were served without an appropriate Content-Encoding
response header, client applications (for example browsers) wouldn't know that they first need to uncompress the response, and thus, wouldn't be able to understand the content.
For example:
<IfModule mod_deflate.c>
<IfModule mod_mime.c>
AddEncoding gzip svgz
</IfModule>
</IfModule>
