Multiple 301 redirects and F5 performance

I assume the application won't redirect the client back to /something/index.htm. How about this then:

 
 when HTTP_REQUEST { 
  
     Check if request ends with /index.htm 
    if {[HTTP::path] ends_with "/index.htm"}{ 
  
       HTTP::respond 301 Location "[string map {/index.htm ""} [HTTP::uri]]" 
       log local0. "Redirecting to [string map {/index.htm ""} [HTTP::uri]]" 
    } 
 } 
 

Note that RFC2616 states the Location header value must be a fully qualified domain name, but browsers accept a local URI. You may want to hardcode the protocol and domain in the iRule.
