can I check what site window.history.back() will bring the user to?

in one of my webpages I want to send the user back to the previous page after some computation, but only if the previous page was a page from my website.

So I am wondering if there is an easy way to check that?

Thank you for any input!

Solution

  • You can however check how you arrived at the current page by using 2 methods:

    document.referrer, but that only works if the user didn't block that, and gives you some limited info. A more robust method might be to set some information about the previous page in either the URL, or in a SESSION variable.
