Exporting an HTTP Archive / HAR
You can export an HTTP Archive / HAR from most modern browsers.
You should be aware the the HAR will typically contain all information from your session, including entered information.
You can record your HTTP session using the Network tab in the Developer Tools in Chrome.
- Open the Developer Tools from the menu (Menu > Tools > developer tools), or by pressing Ctrl+Shift+C on your keyboard
- Click on the Network tab
- 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.
- Check the box next to Preserve log.
- 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
- Save the capture by right-clicking on the grid and choosing “Save as HAR with Content“
Starting with Firefox 41, HAR files can be created without any additional extension.
- Start Firefox Developer Tools in Network mode (Top right menu > Developer > Network, or ctrl-shift-Q)
- Reproduce the issue
- Save the capture by right-clicking on the grid and choosing “Save all as HAR“
- Export the capture to a HAR file
Internet Explorer / Edge

- Open the Developer tools by pressing F12
- Click on the network tab
- To record the session press the start session button at the far left of the network tab (Ctrl + E)
- When you are done with the session, chose the stop button (Ctrl + E again)
