Hey guys,
I'm having a problem, when my server gets DDoS attacked, no PHP applications work but say I try to load like website.com/blahblah or any other page that isn't there that produces a not found output, that's still running quick. How can I tune my PHP application for DDoS?
Thanks,
Hady Abed

You need to restore the default configuration for lsphp.
You can find the default configuration values in lsws-3.3.8/add-ons/directadmin/httpd_config.xml

Mistwang,
Okay, I've restored those values but it seems my PHP is still having issues. I know you don't like providing free support, but if you're willing to take a quick look, please PM me and I'll give you my LiteSpeed Web Admin Login.
Thanks,
Hady Abed

You have done something special for '/home", other pages are working fine.

No, I put up a page saying there was problems with the PHP core, the other pages don't work fine.

all are working fine, only http://hr-development.net/home is broken. it is not a PHP problem, probably a URL rewrite problem if you use URL rewrite to make URL SE friendly.

If you refresh any of those pages about 3 times, it doesn't load very fast, it wasn't like this before.

It looks like firewall or network problem, google "ip_conntrack" and make sure it hsa been set large enough.

It's set to 65536. So many issues lately.

Try to turn off firewall and test again.
