access irule name from inside the irule

I have a customer that has a number of URL's that all essentially serve the same site but with different content based on the url. They have asked to have 4 virtual servers and a unique pool for each site. I would have preferred to do the pool selection in a single irule, but they require a unique irule per site.

 

 

My idea was to include the site name as part of the irule name and use that to make the pool selection, just copying the irule N number of times changing the name instead of coding the site name into 40 different irules.

 

 

Thanks very much for the input.
