hash persistence on an irule manipulating ICAP headers

Hello ,

 

 

Thanks for your response!!!!

 

 

I had the chance today to apply the persistency onsite . Unfortunatelly this does not work , and the reason is the HTTP profile that the hash persistency requires.

 

 

What I noticed in traces is that when I set HTTP profile in the Virtual server then the VS does not forward the full ICAP request in the pool member as seen bellow .

 

 

Any idea how we can overcome that ? any other type of persistency that might be more appropriate fro ICAP VS?
