    Assuming all incoming url starts_with /rec/widgets, you can try below code

Hey Sanjay,

 

Thanks for the quick reply!

 

Does the replacement host "sample.com" have to be in the same LTM? In our case, it's an external address.

It can be hosted any where. You would need to modify the iRule above to create a pool for "sample.com" and use it with pool command before return statement.

​

Make sure pool is reachable from the LTM. ​
