Generating HAR Files
Generate a HAR file to help troubleshoot any issues encountered.
HAR (HTTP Archive) is a file format typically used to export captured data through HTTP session tools. The file format is essentially a JSON object with a particular set of fields.
Notes
- HAR files contain sensitive data, including the content of pages the user downloaded while recording and cookies.
- Use an Incognito Window to collect the HAR files.
- Enable third-party cookies to ensure proper cookie preservation during reproduction.
