Locked requests

In Locked requests you can specify the file types and MIME types (content types for the transferred data) to be blocked by WebGuard. The Web filter lets you block known phishing and malware URLs. WebGuard prevents the transfer of data from the internet to your computer system.

File types / MIME types to be blocked by WebGuard (user-defined)

All file types and MIME types (content types for the transferred data) in the list are blocked by WebGuard.

Input box

In this box, enter the names of the MIME types and file types you want WebGuard to block. For file types, enter the file extension, e.g.  .htm. For MIME types, indicate the media type and, where applicable, sub-type. The two statements are separated from one another by a single slash, e.g. . video/mpeg or audio/x-wav.

Note
Files which are already stored on your computer system as temporary internet files and blocked by WebGuard can however by downloaded locally from the internet by your computer's internet browser. Temporary internet files are files saved on your computer by the internet browser so that websites can be accessed more quickly
