how to forward a link with URI to another link with the same URI

Question

My program directs users to a webpage with their username and password. E.g. http://example.html?username=username&password=password.

Now I created another page in asp.net and I want some code on example.html to redirect the link to http://example.aspx?username=username&password=password.

So what i want is to get the URI from the first url and direct it to the new url by appending the URI.

Any suggestions?

You can grab the querystring in its entirety via

window.location.search

See this with more about that. Using this, you can extract the parameters, append them to a new URL, and render the link, or set

window.location = "example.aspx" + window.location.search

I believe search comes with "?", but I could be wrong. I assume this is an exmaple; note it's not a good practice to pass the password through a querystring as clear text, especially if you are not using HTTPS. It's generally advisable to do a POST operation, not a GET operation with querystring, when it comes to sensitive information.
