NimbostratusWant to rewrite part of host

If string position is known then you can use
function to grep value like below.getfieldset 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 aaaRefer below link. Hope it will be helpful.
