How to download files larger than 1 GB through the Finjan


  • Description

    There is a hard coded limitation of 1 GB filesize.

  • Symptoms

    If a file that is larger than 1 GB is requested by the client through the Finjan, the proxy will return an error:

    Error Occurred
          HTTP Error Status: 403 Forbidden
          Error Reason: Response body too large Please contact your system administrator

    Without a reason being given in the web log.

  • Cause

    NOTE: This will not work if the server does not reply with correct headers, such as in the example below:
