Is it correct to use Javascript for redirection?

My asp.net base page redirects to the login page automatically with the following code in case of authentication issues:

response.write("<script>window.open('" & LoginPage & "','_parent');</script>");

I'm wondering if there is a security risk with using JavaScript to redirect to another page. Is it secure?

Answer №1

It is crucial to always sanitize user input to prevent potential security threats. If the LoginPage variable originates from user input, it could lead to a security issue if not handled properly.

For more information on sanitizing input in classic ASP, you can refer to this helpful thread: Good way to sanitize input in classic asp

Remember that JavaScript operates on the client-side and does not impact your server directly.
