Securing and inserting registration info into secure database

Hi Keefaz,
But still the curl will show the HOST2 ip right ? So with curl I will still need to pass data and would that show up ?

No, curl won't show anything on client visiting HOST1, it's processed on the server side. Curl will act like a client to HOST2, sending request, passing data, receiving answer but client from HOST1 has no way to see what HOST1 is executing.
