Hi,

I have a fairly busy server (around a million visitors a day) and until very recently my "Connections: HTTP Used" used to be around 300-500 constantly.

Now though, it is between 0 and 4.

My server is responding fine though and the amount of traffic is the same, just for some reason had a dramatic drop in the amount of http connections used.

Is this correct or some sort of bug?

Req/Second is around 400 still.

The only thing I can remember doing is reducing the Keep-Alive Timeout (secs) by a couple of seconds.

Just curious as to why this would happen?

Many thanks,

Ian

Hi Ian,

Can you provide the following info?
1. Your OS version
2. Your LSWS version
3. Keep-Alive Timeout setting (before and after)

Hi,

I just thought of one major thing that could have affected it..

The webserver is now behind a reverse proxy server - would this cause the amount of connections to become only 1 or 2?

I notice when accessing my server through the proxy the following header is set:

[HTTP_CONNECTION] => close

where before it was:

[HTTP_CONNECTION] => keep-alive

1. Your OS version
Red Hat 4.1.2-48

2. Your LSWS version
Enterprise Edition - Version 4.0.17

3. Keep-Alive Timeout setting (before and after)
5 and 3 (but possibly this is being overridden by the proxy server?)

Thanks.

Hi Ian,

4.1.2-48 is probably your gcc version.

Pls do 'cat /etc/redhat-release' to show your OS version.

Also post a screenshot for your real time stats.

BTW, just for better understand your situation, what is the purpose of your reverse proxy? what are the settings?

Sorry for the delay..

OS Version:
CentOS release 5.5 (Final)

I've attached screenshot (which seems to have shrunk - let me know if you can't read it).

The reverse proxy is for DDoS protection, couldn't tell you of the settings I'm afraid.

Like I said, the server is working fine - just used to having 300-500 http connections used instead of 2.
