    Strange behaviour on large file upload

    iain.gardiner

      Hi anyone have any idea about this one.

       

      Our customer is uploading a file to a site over https using their activex upload wizard. At this stage there are no exceptions in our rule base for the site. We are using the standard SSL scanner rule.

       

      File 1 is 6mb in size, auto generated from a backend system as a csv. It uploads OK and passes the file integrity check. During tracing I noted the following values:

      Media type from HTTP header = text/plain

      Enshured media type = application/x-empty

      Supported by opener = false

       

      File 2 is 30mb in size, auto generated from a backend system as a csv. It appears to upload OK but after the file integrity check I get a failure message 404. Again during tracing I noted the following values:

      Media type from HTTP header = text/html

      Enshured media type = text/html

      Supported by opener = true

       

      The only way I can get the large file to upload is by tunnelling the site.
