iRule for caching

dear All,

 

I am new for iRule, i have a LTM setup that is load balancing the proxy pool (Proxy1,Proxy2,Proxy3) When one user access the youtube video through proxy2 and the another user accessing the same video but the traffice should go to proxy2 only because of caching... i hope you understand my needs... i want i rule for caching for the above setup...

    Hi Moorthy,

     

     

    CARP hashing should work well for this:

    Hi Moorthy

     

     

    Sorry for that question but I'm just wondering.

     

    You have loadbalanced proxies for your users right?

     

     

    They can surf arround youtube during business hours?

     

     

     

    Kind regards
