Web server connection duration

[#1]

Hi,

I have web application running on HP-UX 11.31.

My clients are bale to connect my web server on port 443 over the internet.

As per my network logs I have found that some of my clients are connected to

my web server for more than expected time (more the 1 Hrs.).

As per my application behavior other clients gets disconnected after 20 to 30 Seconds.  

Please help me to find out the duration of connection (from clients IP to my server IP on port 443) at server level.

Can you look at the your web server logs?

I can find the connection time (when client was connected to my server on port 443) from the application log, but can’t find out when it get disconnected from my server.

I want to know the time duration of that connection.

Is there any way to find out the connection duration at OS or Network level ?

Any suggestions....?
