URI redirect to specific pool

Apologies in advance if this has been asked 100 times already....

 

 

I would like to redirect requests for a specific script or perhaps folder to a specific pool because of some load generated by this script.

 

 

For example, I would like to have requests for this page

 

 

http://example.com/sampler/qpercent.phtml

 

 

redirected to

 

 

pool_limited

 

 

and if not it goes to the default pool for that virtual server.

 

 

Is there any examples of this?

 

 

Thanks
