Load balancing of Bluecoat proxy SG in active-active

Hi,

 

 

Can we laod balance Bluecoat proxy SG in active-active mode.

 

 

Bluecoat proxy SG is used for caching.

 

 

so, probably F5 will be placed inline between firewall and router, and it will redirect all the request coming for internet to bluecoat and then request will be forwarded to internet via internet router. once responce comes from internet it should be redirected back to bluecoat, so that content can cached.

 

 

Can some body help with the configuration required to be done on F5. Because its a cache-redirection load balance not a simple load balancing.

 

 

Regards,

 

 

Ravi

    Hi Ravi,

     

    Usually the F5 is placed behind the firewall where the firewall is the default route. In this scenario you would create a Virtual Address with pool members to 2 BlueCoat Proxies. There Destination Persistance would be turned on and applied to the pool members. The clients accessing the proxy simply points thier browser proxy setting to the virtual address on port 80 or 8080. This would do the trick.

     

     

    However, I making some assumptions about your network so it might differ then what you want.

     

     

    Hope this helps
