HAR (HTTP Archive) is a file format used to track all the logs of a web browser's interaction with a website. It can be a requirement for troubleshooting technical issues such as long page load to the computer’s processor, bottleneck, timeouts when performing certain actions, missing information, etc.
HAR files can be highly useful because they provide additional information about the network logs and requests generated when an issue occurs on your local device, internet connection, and browser.
Providing these HAR files to our LearnWorlds support team will help expedite the troubleshooting process and assist you in a timely manner.

HAR files contain sensitive data (downloaded content while recording and cookies). This allows anyone with the HAR file to impersonate your account and see the information captured while recording (e.g., personal details, passwords, etc.) Ensure that you send the file to the LearnWorlds support team and not to an untrusted person. You can remove or obfuscate any sensitive information (such as passwords and client secrets) using a text editor.
