Stickiness Troubleshooting and stickyDebug

Does anyone know how to use stickyDebug?

We have set up an Internet facing Web Hosting facility with two Apache servers behind a CSS11051. We have configured several of the available types of stickiness and the server people keep telling me that it is not working and that sessions are drawing pages from both servers even when sticky is configured. Any advice on how to see what the CSS is doing with the sessions will be much appreciated. Thanks.

No one can help you if you do not post your configuration here.

Re: Stickiness Troubleshooting and stickyDebug

As the previous person said, it would help to have the config. Quite honestly you probably have a persistence issue thus you should add "no persistent" in the content rule and add "persistance reset remap" in the global section of the config. Give that a go

Re: Stickiness Troubleshooting and stickyDebug

Here is the relevant part of the config.

We have also tried

sticky-srcip on it's own

cookies on ports 80 and 443

arrowpoint-cookies on ports 80 and 443

Cheers

Try the persistent stuff I mentioned in the previous post

Re: Stickiness Troubleshooting and stickyDebug

We discovered that ssl encrypts cookies even if generated by the CSS - should have guessed it perhaps. So cookie methods would never work.

ssl session id did not work because IE renegotiates ssl session every two minutes - see http://support.microsoft.com/default.aspx?scid=kb;EN-US;265369

srcip did not work UNTIL we did a reboot and then it worked! Seems like changing content rules on the fly may NOT be foolproof.
