hostname rewrite

HI hoolio, I wrote up the iRule I think that should work (I have not tested this yet...I'm hoping to test this early next week).

In a nutshell, on HTTP_REQUEST..I'm going to rewrite the HTTP host header from aaa.company.com to bbb.company.com and on the HTTP_REQUEST, if HTTP header "Location" exists, I'm going to rewrite Location value from bbb.company.com to aaa.company.com (Is that a valid task to rewrite the Location? Do I need to rewrite the hostname anywhere else?). Again, I don't know if this is going to work or not...

 
  when RULE_INIT {        
 set ::external_hostname "aaa.company.com"         
 set ::internal_hostname "bbb.company.net"    
  Enable debug logging to /var/log/ltm.  1 = yes, 0 = no 
 set ::hostname_rewrite_debug 0 
 }    
  
  
 when HTTP_REQUEST {                
 if {$::hostname_rewrite_debug}{log local0. "Original URL: [HTTP::host][HTTP::uri]"} 
  
 HTTP::header replace "Host" $::internal_hostname        
  
 if {$::hostname_rewrite_debug}{log local0. "New URL: [HTTP::host][HTTP::uri]"} 
 }    
  
  
 when HTTP_RESPONSE {         
 if { [HTTP::header value "Location"] starts_with "$::internal_hostname" }{ 
  
 if {$::hostname_rewrite_debug}{log local0. "Inside of HTTP::header location, orig HTTP location equals: [HTTP::header location]"} 
  
 set ::location [HTTP::header location] 
  
 HTTP::header replace location $::external_hostname 
  
 if {$::hostname_rewrite_debug}{log local0. "Inside of HTTP::header location, new HTTP location equals: [HTTP::header location]"} 
 } 
 }
