HTTP Archive Viewer – a handy tool for troubleshooting web pages. Â Here is how to use it:
- Open Google Chrome browser (new tab).
- Press F12 to open Developer Tools.
- Switch to Network tab.
- Load any page in the tab.
- Right-click anywhere over network requests to get a menu.
- Select ‘Save as HAR with content’.
- Choose the location for the HAR file.
Now you can drag-n-drop this file into the HTTP Archive Viewer and study how the page loaded, which requests were made, how much time was spent and how it was spent. Â This is particularly useful for the following scenarios:
- You are about to make some changes to your site, and you want to compare ‘before’ and ‘after’.
- You are troubleshooting a session of a non-technical user, who can’t provide you access to his desktop environment.
