How To: Collect a .HAR file

Often, it can be useful to get the header information for a page for troubleshooting purposes. The easiest browser to accomplish this with is Google Chrome. If you do not have Google Chrome, you can download it for your computer for free at chrome.google.com. Once you have done so, follow the instructions below to capture the headers:

Before we load the troublesome page in Chrome, open a new incognito window and right-click anywhere in the page. Select "Inspect Element."

This will open the Developer Tools window. We will use both this and the browser window to capture the headers.

 

  1. In the browser window, navigate to the page that we need the headers from.
  2. In the developer tools, click the "Network" tab at the top. It looks like this:
  3. Make sure that the disable cache check box is selected
  4. Refresh the webpage. This will load the data from the page into the Developer Tools. 
  5. Right-click in the area labeled "Name" and Select "Save all as HAR with Content
  6. Save the file to your computer.
  7. Attach the .har file to an email and send it to support@yottaa.com.

These .har files are very useful in troubleshooting situations.
