Sanitizing input data from text boxes

[mbosco51]

Hi. I maintain an asp website with many input text boxes. I need to
check all the data that is typed in for special chars. What is the
best way to do this? I need something that will always run, regardless
of browser settings (disabling of javascript, etc...). Thanks.

The only foolproof way to do this is to check the data on the server
after it's been submitted. If it doesn't meet with your standards,
then send it back to the client along with an error message.

Thanks Tim. That's where I get confused though. How do I ensure that
I'm "on the server"?

If you don't know that, you need some very basic education about ASP.
Here's one site that might be of aid: http://www.learnasp.com/learn/

Google for others.
