Troubleshooting: HAR files

We occasionally need additional information from users when they experience an issue which we can't replicate. The best way to gather this data is via a HAR file. Below are the instructions as to how to gather a HAR file, which you can copy and paste into an email:

To help the team continue to troubleshoot here we'll need you to provide some more extensive data via a HAR file. We've outlined below the steps user needs to go through to generate the file, depending on their browser.  

➤ Internet Explorer/Edge

Edge natively produces HAR files. See detailed instructions in the Microsoft site

• Open the Network tool in F12 developer tools
• Reproduce the issue
• Export captured traffic as a HAR (CTRL + S)

For Internet Explorer, you will need to use: HttpWatch 

• Download and Install HttpWatch
• Start the HttpWatch capture right before reproducing the behaviour you want to study
• Stop the HttpWatch capture right after reproducing the behaviour to study
• Export the capture to HAR format

➤ Firefox

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

➤ Chrome

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"
