Redirect or rewrite?

Hi,

 

 

I would advise not to use matches_regex since it will take more CPU. Regular expression is really CPU expensive:

 

 

 
   when HTTP_REQUEST {    
     if { [string tolower [HTTP::path]] eq "/foo/"} {    
       if {([IP::addr [IP::remote_addr] equals 10.12.126.248/255.255.255.255]) or    
       ([IP::addr [IP::remote_addr] equals 10.12.126.249/255.255.255.255]) or   
       ([IP::addr [IP::remote_addr] equals 10.12.126.250/255.255.255.255]) or   
       ([IP::addr [IP::remote_addr] equals 10.24.69.2/255.255.255.255])   
       } {    
         pool FOO.com-80    
       }    
     } elseif {[IP::addr [IP::remote_addr] equals 10.0.0.0/255.0.0.0] } {    
       HTTP::redirect "http://www.NEW.com"   
     }    
   }    
 

 

 

In this code [HTTP::path] will return the Path AND the object name. May it be the reason why it doesn't match? Click here

 

 

You should try to replace the eq by contains or starts_with w(starts_with will be more efficient)

 

 

Can you update your iRule with troubleshooting information and give us the logging (is it in /var/log/ltm)

 

 

 
   when HTTP_REQUEST {    
     log local0. "---------NEW REQUEST--------------" 
     log local0. "uri is: [HTTP::uri]" 
     log local0. "IP is: [IP::remote_addr]" 
     if { [string tolower [HTTP::uri]] starts_with "/foo/"} { 
       log local0. "Starting uri with /foo/" 
       if {([IP::addr [IP::remote_addr] equals 10.12.126.248/255.255.255.255]) or    
       ([IP::addr [IP::remote_addr] equals 10.12.126.249/255.255.255.255]) or   
       ([IP::addr [IP::remote_addr] equals 10.12.126.250/255.255.255.255]) or   
       ([IP::addr [IP::remote_addr] equals 10.24.69.2/255.255.255.255])   
       } {    
         log local0. "sending to pool FOO.com-80" 
         pool FOO.com-80    
       }    
     } elseif {[IP::addr [IP::remote_addr] equals 10.0.0.0/255.0.0.0] } { 
       log local0. "Redirecting user..."    
       HTTP::redirect "http://www.NEW.com"   
     }  else { 
        log local0. "No matched occured for this request" 
    }  
   }    
 

 

 

I added a last else statement for more logging information. Once it is fixed you should of course remove it
