How to generate a HAR file?
HTTP Archive (HAR) stores all web requests made by the browser, including:
- The request and response headers and bodies.
- Connection, response, and download times.
- Failed requests or network errors.
HAR files help troubleshoot issues related to speed, caching, performance analysis, and security assessments. Please follow the steps below to generate a HAR file based on your browser.
Prerequisite: Be on the page where you encountered the issue.
For Google Chrome
- Right-click the page > Inspect.

button. Refresh the page and repeat the action that caused trouble to capture the issue as output.
