irule for redirection of url is notworking as expeced.

Hi All, I have new rule configured

when HTTP_REQUEST { if { (([HTTP::host] equals ";) or ([HTTP::host] equals "198.x.x.x.")) } { HTTP::redirect "; } }

I have create New VIPs for stage.omega.com which hasNATed public ip with 198.x ip along with public DNS which works fine with DNs as well as IP ,I have created one more vip stage.mega.com and NATED with public ip and public DNS and taged the above irule into stage.mega.com vip to have redirection that if any user hitting https://stage.mega.com should redirect to https://stage.omega.com.

redirection is working fine when i access the but it is not working when i access the url like https://stage.mega.com

can some one let me know if i am missing or need to add any thing to irule ?
