CSS keepalives

[jonhall01]

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.

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 192.168.30.27:80(-) KeepAlive probe (11)

IP Address: 192.168.30.27

See what it gives you.

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