HTTP Host modification

Howdy all,

 

In the middle of a mid-sized data center migration for our clients to a new set of F5s. We want to give clients the ability to test migration before we move them permanently. The idea is to give them a test URL or testclientname.companyname.com but have an iRule trim the "test" off the http host and redirect to their new production url clientname.companyname.com. Is that something that is possible?
