Why when enabling the Keep-Alive fails with error 500?

Decided to include in the htaccess Keep-Alive, ordered the command Header set Connection keep-alive timeout=15 it gives an error 500. Why?

Maybe you need quotation marks, all the same parameter (the header) contains a space:
Header set Connection "keep-alive timeout=15"
?
Changed, but nothing has applied - Ulices commented on March 19th 20 at 09:27
