Data validation from another server

[enterume]

Please advice on how can create a more secure page for data validation.

Basically I have a page to pass all the user's input, to validate from a server. At the end of the validation, some return variable will return from the validation process.

How could I hide the url from the user to see from the status bar(while validating), and get the return result, in more secure process?

Would CURL help in this? Or any other example on this?

Thanks in advance.
