How to read source IP and write http header ?

Hi Eric,

 

 

The following is a untested iRule that may work for you

 

 

 

  
     when HTTP_REQUEST {  
       Create the variable that will be used to later to store the IP address with the dots  
       set ipaddr  
         
       Scan command looks at the source address in [IP::client] and breaks it up into 4 variables oct1 to oct4  
       scan [IP::client] {%[^.].%[^.].%[^.].%s} oct1 oct2 oct3 oct4 
         
        append takes all the variables oct1 to oct4 and puts them together into another variable called ipaddr  
       append $ipaddr $oct1 $oct2 $oct3 $oct4  
         
        The command below inserts a header called TOTO with the value of what's in ipaddr  
       [HTTP::header] insert "TOTO" $ipaddr  
     }  
  

 

 

I have made comments in the code so you understand the logic behind it

 

 

I hope this helps
