Direct the user to a webpage with the option for postback functionality or caching

I'm encountering an issue on my webforms site with 2 menus. When a button is clicked on a page, it triggers some C# events through a webservice (ajax) and then redirects to another page using history.go(-1). The problem arises when I create a session in the webservice that causes the menus to switch - the default menu hides and the other one shows. This menu switching logic is implemented in the Page_Load event of the Master page.

The issue occurs when using history.go(-1) to return to the previous page, as the old menu persists instead of displaying the new one. How can I resolve this dilemma?

Answer №1

The issue at hand is that the browser isn't actually loading the previous page; it's using the cached version instead. Have you considered keeping both menus hidden and then determining which one to show on the client side? This way, you can use JavaScript .ready function to decide which menu to display, ensuring the desired outcome when using history.go(-1).

This article suggests setting a cookie from the server and then checking for it on the client-side. By implementing something similar, you could examine the cookie to ascertain if the page was loaded from cache and trigger a postback if needed.

window.location.reload()

Answer №2

To solve the issue, I included the previous link in a session and set up a redirect to another aspx page with caching. The redirection destination is determined based on the URL parameters. This approach seemed like the most straightforward solution.
