how to prevent loading querystring parameter again

Question

Hi,

I have a website that has two pages. First one lists intern email. once an intern click on his email, it takes him to another page pulling his profile information from the database for an update.

internship/internProfile?internId=61  // in the URL address

 

once the intern click update his information, the form clears its data.

 

My issue is when I change the value of the querystring from the URL address, it keeps pulling intern data for any intern from the database. My quesiton is how to prevent this .

 

Appreciate your advise,

 

Al
