Show/Hide Article Tools


  • 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

    The largest file-size that is limited to traverse through the Finjan is 1 GB. This limit is hard coded and can not be increased through the GUI.

  • Solution

    In order to circumvent this issue, please follow the steps below:

    1. Create a header fields list (please note the correct header name "Content-Length"):

    Define a header value of ~ 1 GB (in Bytes, e.g. "1048576000"):

     

    2. Create a rule using the header list as a condition:

     

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

  • Software Version
    9.0
    9.2
