An HTTP Archive file (HAR) is a JSON-formatted log file of a web browser's interaction with a site. HAR files help Candu Support diagnose technical issues by showing the behind-the-scenes network activity when you run into a problem.

When you need a HAR file

Candu Support may request a HAR file when you're experiencing:

  • Performance problems with content loading or rendering

  • Network errors or timing issues with Candu requests

Generating a HAR file takes about 1-2 minutes.

Before you start

For best results:

  • Follow the exact steps that reproduce your issue

  • Identify the specific page URL where content should appear

  • Close unnecessary tabs to reduce file size and noise
