Multiple Redirects

Question

I have several Host Headers setup in IIS for one website: 
&nbsp;  
&nbsp; ex: nnn.sitename.com 
&nbsp;  
&nbsp;  
&nbsp; I need to write a rule for www.nnn.sitename.com to redirect to nnn.sitename.com 
&nbsp;  
&nbsp; This needs to be done for at least 10 URL's.  
&nbsp;  
&nbsp; What would be the best way to tackle this? 
&nbsp;  
&nbsp;  
&nbsp; Thank you in Advance!!!

if it is always the same format like www.[host] need to be redirected to [host] then a simple iRule that extract the first part should do the job 
  
 But if it is not so consistent, you can build a datagroup which says for each host what should be the redirect  
  
 ex: 
  
 this class definition is what you see in your bigip.conf file when you define a datagroup 
 class hostredirects { 
   "www.nnn.sitename.com http://nnn.sitename.com" 
   "www.nan.sitename.com http://someotherhost.nowhere.com" 
 } 
  
 when HTTP_REQUEST { 
   set location [findclass [HTTP::uri] $::hostredirects " "] 
   if { $location ne "" } 
     HTTP::redirect $location  
   } 
 }

I am still learning my way around the BigIp. Where do I define this data group? Also,removing the www sounds like a good option. Can you show me an example?

In the GUI it is a tab in the iRules section at the top of the editing window.  In the CLI, it is called a class, and can be defined with the bigpipe class command.
