- Attach the HAR file and HTTP Error file to the case, or use CB Vault if the file is larger than 25 MB
Additional Notes
- All credentials and session cookies within a HAR file should be removed before sharing with Carbon Black
- The HAR file is a text file, it can be opened in a text editor and searched for the SESSION cookie value and replaced with
<REDACTED> - This can also be done for passwords and API tokens if they were part of the recording
- It's also recommended to logout from the Carbon Black session after recording a HAR session. This is a precaution that should invalidate session IDs if any were missed.
- HAR Files under 25 MB can be attached directly to a Carbon Black Technical Support case.
- Files larger than 25 MB should be uploaded to CB Vault.
