Problem Description

Browser debug logs can be used to help troubleshoot why a web page is not opening, partially loading, failing to redirect and latency issues. This article explains the process for collecting these debug logs from different browsers.
 

Resolution

The HTTP Archive format (HAR), is a JSON-formatted archive file format for logging a web browser's interaction with a website.
These network traces help capture the http request as its leaving browser and the response received from the client's browser perspective.
Please consider reviewing the collected file for any privacy & security sensitive information before sharing the .har trace with Forcepoint Support.
