URL Browser Mask/Hide with redirect

Hello,

I have a URL forex.mycomp.com:443/forex this URL use some Users. Now I use this iRule

when HTTP_REQUEST { set uri [string tolower [HTTP::uri]] if { $uri eq "forex" } { HTTP::uri "*" HTTP::header replace Host sap10.company.company.de } }

to get access on sap10.company.comany.de:8445/forex on the realserver, now what I want to do is to display in the browser just forex.mycomp.com:443/forex and not to switch to sap10.company.comany.de:8445/forex, I did try to figure out, for example with the proxy pass iRule, but these are really complex things and I need help, maybe I could get a easy example iRule from someone which resolve my wishes. Other thing is I know that this use case didn't work together with a redirect ! So I search for a GOOD answer how can I solve this topic. I hope for a example iRule maybe from a User with a big knowledge in iRules, more than mine. It is all https traffic and a valid certificate is inside the VS.
