Good afternoon,
I have used several online tests to see how to improve and optimize the web page that I am developing before publishing it, but they tell me several things that I do not know how to solve.
Accept-Encoding Header
I have put this code in the .htaccess and I have solved others that came out, but this one I do not know because it keeps coming out:
<IfModule mod_headers.c>
<FilesMatch ".(js|css|xml|gz|html)$">
Header append Vary: Accept-Encoding
</FilesMatch>
</IfModule>
--------------------------------------
Would anyone know how to solve this problem?
Many thanks in advance!
