Generating a HAR file
Stanza support may occasionally need additional information about the network requests that are generated in your browser. A member of the team may ask you to record a HAR file, or a log of network requests, while that issue occurs.
Note: A HAR file includes data such as the content of your cookies and the pages you downloaded while making the recording. Anyone with access to the HAR file can view the data submitted while recording, which may include personal data or other sensitive data. Make sure that you secure your HAR files accordingly. Cloudflare has released a HAR sanitizer that can be used to strip any sensitive information.
