Symptoms

When you click the Back button in Internet Explorer 11 to go back to a previous page, the Onload event of the page may not occur.

Cause

This issue occurs because the back navigation caching restores the contents from memory instead of reloading or reconstructing the page.

Resolution Method 1: Use the onpageshow event

Use the onpageshow event instead of the Onload event. Onpageshow events occur when you click the Back button.

Resolution Method 2: Disable the back navigation caching

Prevent the web pages from meeting any of these conditions, so that back navigation caching does not occur:

• The page is in the Internet zone.
• The page is served by using the HTTP protocol (HTTPS pages are not cached for security reasons).
• The page has no beforeunload event handlers defined.
• All load and pageshow events are complete.
• The page does not contain any of the following items:
  • Pending indexedDB transactions.
  • Open or active web socket connections.
  • Running web workers.
  • Microsoft ActiveX controls.
• The F12 Developer tools window is not open.
