Header Insert

You can checkout the HTTP::header documentation in the wiki for manipulating headers.

Specifically if you want to add the client address to a header going to the destination server, you can do so like this:

when HTTP_REQUEST {
  HTTP::header insert "ClientIP" [IP::client_addr]
}

Or you can create a custom HTTP profile, and add the following line as the header insert value. Which ever VIP you have the custom HTTP profile applied to, will have the client IP inserted into a header; unless it is encrypted traffic.

 

 

x-client-ip:[IP::remote_addr]
