Pages do not load correctly only when you click the Refresh button on Win7 + IIS7.5

Question

I recently migrated my development website from an old computer (WinXP with IIS5.1) to a new computer (Win7 with IIS7.5). The application is developed using ASP.NET with a bunch of javascript and CSS files.

On the new computer, the virtual directory is created by default by default, but includes ASP.NET Impersonate and Windows Authentication (anonymous disable)

The application uses the classic Pipeline on the .NET.NET AppPool (.NET 2.0), which comes with IIS7.5.

With the above configuration, the application works fine on IIS5.1, but not on IIS7.5. The page will load correctly, but if the refresh button is pressed, the page will load incorrectly, displaying only the ASP.NET page without loading JS and CSS.

However, having renamed the URL in the address bar and press Enter to reload the page, it will display correctly.

At first I thought about it because IE9, but I can use IE9 to open the application on an old computer without any problems.

If anyone knows any tips, please tell me.

thanks
