Rewrite URL and Virtual Server Selection

Hi All,

I have 2 web server url binding to 2 VS in F5,

1. oa.f5.com = VS_OA
2. office.f5.com = VS_Office

I want to achieve, if the user type http://oa.f5.com/nadine then it will go to http://office.f5.com/

I have created the irule in VS_OA as below, but no success ( the traffic still go to VS_OA with error 404 due to no nadine folder)

when HTTP_REQUEST_RELEASE {

 if {[string tolower [HTTP::host]] starts_with "oa.f5.com" && [HTTP::uri] starts_with "/nadine" } {

  HTTP::host "office.f5.com"

  HTTP::uri [string map {"/nadine" "/"} [HTTP::uri]]

  virtual VS_Office

 }

}
