Want to rewrite part of host

Hi guys, I'm still new to iRules, I wonder that if it is possible that an iRule can rewrite part of the host instead of all of it. I mean like, if a client request a host like "123.aaa.com/888/"...

If string position is known then you can use

getfield

function to grep value like below.

set hostname [getfield [HTTP::host] "." 1]   If the URL is xxx.aaa.bbb.com, then getfield command will grep value of 1st position xxx
set hostname1 [getfield [HTTP::host] "." 2]   If the URL is xxx.aaa.bbb.com, then getfield command will grep value of 2nd position aaa
