Viewing Source Code

Question:
Is there a way to prevent users from using the VIEW/SOURCE to view the HTML in my pages? I need to have this for a form that uses sensitive information in the VALUE field of a drop down menu, and I don't want anyone to be able to just go in and view the source code to retrieve the values.

Answer:
There are a number of workarounds that can keep some people out of your source, but there is no way to keep all people out of your source.

If keeping 99% of the people out of your source is okay, you'll want to (1) keep out all non-IE users, (2) keep out all non-Windows users, and (3) keep out all users without JavaScript. Then, you can use JavaScript to capture the right-click of the mouse, which will keep some people from viewing your source.
