HTTP Return Code on CSM causes IP Sticky does not work

budiman — Fri, 07 Feb 2003 07:49:18 GMT

I have CSM running on 3.1(1a).

I configured HTTP Return Code Checking:

map HTTPCHECK retcode

match protocol http retcode 404 404 action remove 5 reset 60

And apply it to the following web server serverfarm:

serverfarm DCMSWEB

nat server

no nat client

predictor leastconns

retcode-map HTTPCHECK

real 10.1.31.1

inservice

real 10.1.31.2

inservice

I also configure IP sticky for my web server:

sticky 2 netmask 255.255.255.255 timeout 60

And apply that sticky to the virtual server:

vserver DCMSWEBHTTP

virtual 10.1.30.100 tcp www

serverfarm DCMSWEB

sticky 60 group 2

replicate csrp sticky

replicate csrp connection

persistent rebalance

inservice

But, the problem is my sticky does not work if I apply HTTP return code checking on the serverfarm.

"show mod contentswitchingmodule 8 sticky" does not show any IP sticky connection.

If I remove HTTP return code checking from serverfarm, my IP sticky is back to normal.

Has anyone encoutered this similar problem before?

Is this a bug on the CSM software?

This is a new bug.

The workaround is to use the command 'client 0.0.0.0 /0' under the vserver.
