set HOST [string tolower [HTTP::host]]
if { (not ($HOST eq "abc.host.com")) or
     (not ($HOST eq "xyz.host.com")) } {

    Thanks Vijay,

    Let me know if I did something wrong, but I entered the rule like this:

    when HTTP_REQUEST {

    HOST = [string tolower [HTTP::host]]

    if { (not ($HOST eq "abc.host.com")) or

       (not ($HOST eq "xyz.host.com")) } {

        HTTP::header replace Host "abc.host.com" 

      } 

     }

     

    And it gave me this error: 01070151:3: Rule [/Common/rule_header_replace_abc] error: /Common/rule_header_replace_abc:2: error: [undefined procedure: HOST][HOST = [string tolower [HTTP::host]]]
