Passing values from one page to another page in JS

I have one query on JavaScript.

How we can pass values from one page to another page?

I am working with ASP.NET. My requirement is, I need to validate the user, whether his session expired or not. If the session expired then I need to show a pop up with two textboxes to enter his credentials.

In which case I was unable to do that in ASP.NET. So though of doing with the help of JS. But not getting ideas.

I know we can pass values from one page to another using querystring. But as per the security purpose that is not to be used in my app.

Please help me out.

Thanks in Advance.

You can save the users info in a session, for example his id and current request time. Then you can compare the previous request time, which you saved while processing the previous request, with the current time. You save the current request time in the session again. If it's been to long ago you show him the login popup. If you need a more secure way of passing the login credentials I recommend using a ssl certificate.

Don't do that on the javascript side. Remember that you can't trust the client side.

Use ASP.NET to do this.

See this tutorial to get some help about using sessions: http://www.beansoftware.com/ASP.NET-Tutorials/Managing-Sessions.aspx

You can set cookies. That's also not really secure, but it's obviously a lot more secure than query strings, though if you're dealing with something that requires more security than what cookies offer, then I would suggest that you're doing something really wrong. (Welcome to Stack)
