Need help with multi domain url rewrite

You've got the right idea, but you can combine that logic into one switch statement.

Try something like this:

when HTTP_REQUEST {
  switch -glob [string tolower [HTTP::host] ] {
    "*abc.com" -
    "*def.com" -
    "*ghik.com" -
    "*lmnop.com" {
      HTTP::redirect "http://www.xzy.com/content.cfm?pageid=11049]"
    }
    "order.ace.com" {
      HTTP::redirect "https://catalog.acme.com"
    }
  }
}

This allows you to expand easily as well, by adding more domains to the list above "lmnop.com" if you need to have more perform the same action later.

HTH,
