How to Generate HAR Files
When you report an issue to Tenna Customer Support, a team member may ask you to record a HTTP Archive (HAR) file or clear your browser cache. A HAR file is a log of the network requests your browser makes while an issue occurs, and it helps Support pinpoint the cause.
Important! A HAR file includes data such as the contents of cookies and the pages you download while you record. Anyone with access to the file can view this data, which can include personal or sensitive information. Secure HAR files accordingly.
