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, be 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.
Note
The list of blocked file and MIME types is ignored if they are entered in the list of
excluded file and MIME types under WebGuard::Scan::Exceptions.
Note
No wildcards (* for any number of characters or ? for a single character) can be used
when entering file types and MIME types.
