How do I extract a HAR file to analyze a webpage?

If I need to work out what is not working for a web page and want to send it for analysis how can I do this?

Sometimes you can see an issue for your site but we cannot replicate the same issue. In this case a HAR record might come in handy for us to diagnose the problem.

Simply go to Chrome.

  • Press Ctrl + Shift + i
  • The Dev Tools panel should open either on the right of screen or on the bottom.
  • Click the “Network” menu item on the top menu bar of the panel

  • Open the page you are having issues on and wait until everything is fully loaded. Make sure the issue has occurred in the current session.
  • Then right-click anywhere on the list of items in the Network waterfall and select “Save as HAR with content”.

  • Save the HAR file and send it to us along with a description of what has gone wrong.

This will provide us with a lot more information to be able to track down the exact cause of the issue.
