I am monitoring my website (faghatseo.com) seeing an error about keep alive. I googled this problem, as an solution, there was a code
<IfModule mod_headers.c> Header set Connection keep-alive </IfModule>
that you had to place in the .htaccess file in this direction below: /public_html/.htaccess
when I placed the code, error 500 appeared and my website went down!
Please contact the server administrator at firstname.lastname@example.org to inform them of the time this error occurred, and the actions you performed just before this error.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
Obviously, I do not have access to Apache cause i'm using shared hosting service.
Is there any other way to enable keep alive with Cpanel or something?
