CSS keepalives

Unanswered Question
May 21st, 2007

Is there anyway of seeing what http response is being returned to a HTTP keepalive on a service. The problem I am having is that the service in question is down. If I change it to a tcp keepalive it comes up. The website is then available. If I use httplook I get a 200 OK. So I can't work out what's keeping the http keepalive down. The site does enforce the use of cookies, and you get an error stating that they muse be enabled, but I still get a 200, so that should be ok I would expect... any help much appreciated.

I have this problem too.

Hello Jon,

Could you please upload the service configuration?

The best way to see what is happening with the keepalive is get a capture between the CSS and the serve. You can use ethereal or wireshark on your server and get the capture.

You will see what the server is responding.

unfortunatly, This is a remote platform, and the customer is not exactly helpfull. I was wondering if the CSS could give me any insite on what its getting back from the server.

you can try something like this :

CSS11503-2(debug)# icp probe service linux1 "/index.html"

Probing KeepAlive probe (11)

IP Address:

Port: 80

URL: /index.html

HTTP Version: 1.1

Server Model: Apache/2.0.46 (Red Hat)

Server Date: Tue, 22 May 2007 11:23:32 GMT

HEAD Response: 200 OK

HEAD Support: Yes

Persistence: Yes

Keep-Alive: Yes

Request Depth: 14

TBR: 44

Hash: 2441da7f68a265f8cfb4426b6897ce33

Connect Time: 2 ms

Rqst/Rsp Time: 2 ms

Pipeline: No


See what it gives you.

But a full sniffer trace and the config would be necessary to really understand the problem.
