Confirming LTM node persistence between pools?

Hi nmenant,

 

 

I can see what you're trying to do (I think - not an expert on iRules). You're basically trying to record the node selected when the LTM does it's thing with the HTTP session, and then re-read the node details and apply when using SSL at the backend (when it's a post).

 

 

Except the LTM moans with a 'Prerequisite operation not in progress' type error - I think this is a chicken and egg situation:

 

The first 'set IP_ADDR... line tries to retrieve the information recorded by the 'when LB_SELECTED' statement, except we haven't chosen a pool at that point, so the session data it's trying to read isn't there.

 

 

Does this make sense?

 

 

I managed to get around this by setting a default (HTTP) pool. But now I can't save my data (my original problem with Sharepoint) :-(

 

 

I'm looking into the options - thanks for the tips.

 

 

Cheers,
