the clients are two different applications. They call the same VIP but using different methods.

 

  1. first client posts a SOAP message to the app servers behind the vip, when this happens, it creates a caseId, which it then passes to another application in next flow. This caseId will be used to continue the processing, which means any further communication using this caseId needs to go to the first server where it was created via Soap Call - as this info isn't shared to the servers behind f5.

     

  2. Later in the flow another application (different client app/server) will call this VIP again but using a GET, passing caseId in the URI being called - this GET needs to go to the server where the caseID was created otherwise the server won't know what it is..

     

the caseId when created is only available in HTTP_RESPONSE data - this I've been able to grab and set into a variable in the irule.

 

thanks
