We have a website that contains encrypted user information in the URL. For example:
www.mysite.com/default.aspx?xs=ew0KICA
Our client reported Bing.com is coming up with that full URL (including the encrypted user information) and is allowing data to be viewed without logging in. How can I prevent Bing (or any search engine) from returning the URL with the user information?
Also, please note that I did not design this site so I'd ask you to avoid comments such as "you shouldn't pass user information that way." It's not how I would have done it, but I need to fix it with minimal time allocated to me to do so. I just need some help figuring out why Bing did this and how to stop it. Thanks!
