Modifying Header Location

I like Joe and Aaron's example. It's easier to understand and very helpful for new people to iRules.

 

I do have a question regarding the use of "Location" here. According to what I can find, "Location" is the whole thing like

 

Location: http://www.w3.org/pub/WWW/People.html

 

 

I wonder if we try to use "host" here since the requestor just want to change from server1 or server2 to www.website.com.

 

Thanks!
