HTTP::header insert

Based on your request

1. For HTTP requests, issue a HTTPS redirect to the client browser.

2. For Non-HTTP requests, insert the "STRING=MLint" header for IIS.

This should work.

when HTTP_REQUEST {
  if { [TCP::local_port] eq 80 } {
     Send HTTP redirect to browser
    HTTP::redirect "https://[HTTP::host][HTTP::uri]test"
  } else {
     Add header with name "STRING" and value "MLint"
     to be sent to backend webserver
    HTTP::header insert STRING "MLint"
  }
}

Now, this didn't include a filter for source IP but that could easily be done with an elseif instead of the else testing for the IP::client_addr against either an address (10.10.10.10), a masked address (ie. 10.10.10.0/24), or an address class using the matchclass command.

Hope this helps...
