Скачать или смотреть Creating a HAR File - Chrome Diagnostics

HAR Files are HTTP Archive files that can get you diagnostics information about your browser session. I used this file to tell me why I was having issues playing video files from my google drive.

Chrome

You can record your HTTP session using the Network tab in the Developer Tools in Chrome.

1- Open the Developer Tools from the menu -Menu - Tools - developer tools-, or by pressing Ctrl+Shift+C on your keyboard
2- Click on the Network tab
3- Look for a round button at the top left of the Network tab. Make sure it is red. If it is grey, click it once to start recording.
4- Check the box next to Preserve log.
5- You can use the clear button a circle with a diagonal line through it right before trying to reproduce the issue to remove unnecessary header information
6- Save the capture by right-clicking on the grid and choosing "Save as HAR with Content"
