TFU flash upload faq image 18. How to configure your firewall/internet security suite.

If you or one of your users has the problem that the progress bar goes very quickly to 100% but no upload finish does appear. Sometimes the upload works if you wait long enough and sometimes it even fails.

I have found out that there are some firewall/internet security suites which are caching the upload and don't deliver the proper return messages to the client. Currently it seems that only Kaspersky products do this. They have an "transparent proxy" where the whole file is cached and therefore the progress bar goes to 100% really quick. All uploads seem to be affected because I have found threads about this problem in other forums as well.

Since TFU/JFU 2.10.2 the flash does detect if an upload is extremely fast and starts an internal timer. If the upload does not finish in time a message box is shown which explains the problem and points the user to this howto.

Here you find the instructions how to configure Kaspersky Internet Security properly. I have installed the German and the English version. So you find the text for both languages below.

Kaspersky Internet Security 2009 (KIS 2009), Security Suite CBE 09:

  • Settings
  • Protection -> Anti-Malware
  • Web-Traffic -> Settings
  • Trusted URLs -> Add the domain where the upload is. e.g. *.tinywebgallery.com* (don't forget the *)
  • Einstellungen
  • Schutz -> Anti-Virus
  • Web-Anti-Virus -> Einstellungen
  • Vertrauenswürdige Adressen -> Hinzufügen der Domain, wo der Upload ist z.B. *tinywebgallery.com* (die * sind wichtig!)

Kaspersky Internet Security 2010 (KIS 2010):

English Deutsch
  • Settings

  • Untersuchung optimieren -> 'HTTP-Datenverkehr von vertrauenswürdigen Webadressen nicht untersuchen' selektieren -> Auswählen

If you have a different firewall/security suite with the same problem please let me know. I will add the instructions then here as well.
