HAR (HTTP Archive Format, .har) is an archive file format with JSON data that stores session data over many browser types (e.g., Firefox, Chrome, Safari, etc.). The HAR file saves the information of all web requests made with the browser.
The HAR file provides a detailed log of all network activity, allowing impact.com solution engineers to investigate a wide range of technical issues.
This includes:
Confirming tracking tags are firing correctly.
Diagnosing display problems, such as pages not loading or platform features not appearing as expected.
Identifying performance bottlenecks, like slow-loading scripts or images.
Analyzing the precise data being sent and received by your browser to troubleshoot complex errors.
