FTP proxy: Upload and download content
You can control the type of files that the FTP proxy allows for downloads and uploads. For example, because
many hackers use executable files to deploy viruses or worms on a computer, you could select to deny
requests for *.exe files. Or, if you do not want to let users upload Windows Media files to an FTP server, you
could add *.wma to the proxy definition and specify that these files are denied. Use the asterisk (*) as a wild
card.
1. Select the FTP Content tab.
2. In the Downloads text box, select the Deny these file types check box if you want to limit the types
of files that a user can download.
This check box is selected by default and restricts the types of files that users can download through the FTP proxy.
3. If you want to deny additional files or file types, type an asterisk (*) and the file name or extension, and
then click Add.
4. In the Uploads text box, select the Deny these file types check box if you want to limit the types of
files that a user can upload. If you select this setting, the files listed will not be allowed.
5. If you want to deny any additional files or file types, type an asterisk (*) and the file name or extension,
and then click Add.
6. Click Submit.
