CSS11500 arrowpoint-cookie question

gfisbeck — Wed, 19 Mar 2003 17:19:02 GMT

I'm doing some testing with a CSS11500 in a one-armed configuration.

I need to ensure that users will stick to the same web server for a period of about 8 hours. I know this can be accomplished with sticky sourceip, but wanted to try arrowpoint-cookies to see how that worked. I believe I have everything configured correctly, but for some reason, I'm not getting any arrowpoint-cookies. Load-balancing is occurring round-robin and there are never any arrowpoint cookies in my Temp Internet Files folder.

Does anyone have any clues?

Config below:

is the clock correctly set on the CSS ?

Could you capture a sniffer trace on the client and see if the CSS

sent something.

Gilles-

Thanks for your reply. The clock is correctly set and is using sntp to keep time synchronized.

I did a sniffer trace like you asked, and I see the page being served from my VIP. I don't, however, see any arrowpoint-cookies. There is a cookie being set, but it is being set by my source server and, unfortunately, does not provide unique information for stickiness.

Below is part of the TCP decode from the sniffer trace:

We ran into the same issue (unable to find the cookie file on the client PC).

A work around is to configure your client browser to prompt for acceptance of cookies and when the prompt comes up, click the "details" button to view the cookie content (you should be able to find the "string" you configured for your arrowpoint_cookie keepalive).

obviously there is no cookie from the CSS.

What software version do you use ?

Could you try to remove the extra commands :

- arrowpoint-cookie expiration

- arrowpoint-cookie expire-services

(just to see if it makes any difference)

I tried removing the extra commands with no effect.

Below is the output of the "show version" command:

CSS11150# show version

Version: ap0500063 (5.00 Build 63)

Flash (Locked): 5.00 Build 33

Flash (Operational): 5.00 Build 33

Type: PRIMARY

Licensed Cmd Set(s): Standard Feature Set

Thanks again for your help!
