XF 1.3 Keep Alive

[DRE]

What is Keep Alive? WebPageTest.org says I don't have Keep Alive Enabled.

http://www.webpagetest.org/result/140216_WC_3GF/

Xenforo 1.3 Beta 3.

All addons disabled on my site.

No social networking integration or buttons.

No advertisements

Default theme with nearly no edits.

I asked my host and they said 'Keep alive is enabled in your server's configuration. If it's off, it's been disabled in your sites' .htaccess file, or otherwise in your code.'

It's an apache setting Dre.

You can see if it's enabled by looking at the apache config in WHM.

Just like my host said, Keep Alive is on.



What on my Xenforo installation is keeping it from showing that it's enabled?

Just like my host said, Keep Alive is on.

Unless your server is under really heavy load, you should keep the Keep-Alive Timeout at 5 (default).

Can you paste your .htaccess, httpd.conf and ssl.conf? I'm guessing there's a rouge 'nokeepalive' somewhere.

Alternatively, you could try the following:

cd /etc/apache2
grep -Rni 'nokeepalive' *

@DRE, can you show me your httpd.conf and ssl.conf files, too?

Or just run the grep command.

Looks like this is some good stuff: http://ausweb.com.au/technobabble/2012/07/27/apache-optimization/

Glad I'm not the only one who is having this issue.

I've been reading a lot and I'm seeing that this Keep Alive issue is actually server related and not software related.

http://www.webpagetest.org/forums/showthread.php?tid=12624&highlight=Keep+Alive

"That means keep--alives are not really enabled. I'm partially convinced that hosting providers were doing that just so you thought it might be while still allowing them to disable it but when the browser sees that "close" it will close the connection.

The keep-alives are generally controlled at the server level and not controllable in .htaccess. You'll need to reach out to your hosting provider."

This guy says it may be related to SSL

and this guy fixed it by editing his SSL v host file.

I put this at the top of my .htaccess

<ifModule mod_headers.c> Header set Connection keep-alive </ifModule>

At the suggestion of: http://stackoverflow.com/questions/8232068/how-can-i-enable-keep-alive

Ended up getting this weird result: http://www.webpagetest.org/result/140217_5P_6J6/



That's weird so I removed it.

Okay so WebPageTest.org has been giving me a False Positive because GTMetrix says Keep Alive is on.

Guess I'll just move on to the next step, fixing First Byte Time.

Strange but Keep Alive is now showing on my WebPageTest.org score after I moved to LiteSpeed.
