stripping data

In this example you are doing the getfield twice which is causing double string allocations. If all you want to do is check whether a "www." is prefixing your domain, you can do so with the "starts_with" operator. And then, since you know you want to strip off the first 4 characters, you can use the "string range" command to do that.

 

 

This code will set a variable to the value of the requested HTTP::host. If that value starts with a "www.", it will strip the "www." off and assign that to the variable. It will then issue a redirect with either the original or stripped host value.

 

 

when HTTP_REQUEST { 
   set host [HTTP::host] 
   if { [HTTP::host] starts_with "www." } { 
     set host [string range [HTTP::host] 4 end] 
   } 
   HTTP::redirect "https://www.domain1.com/nsa/+homePage=$host" 
 }

 

 

Is this what you are going for?

 

 

Oh, BTW, make sure you don't have this iRule on your www.domain1.com virtual or you'll get yourself into an infinite loop.
