4. If you wish to filter all the available file extensions, then you can click the
‘Select All’ button located in the bottom of the page. This will place a check
mark for every file extension. A second click the ‘Deselect All’ button will
remove the filter on all content types.
5. If you wish to enter your own custom file extensions, you can type these into
the ‘other file extensions’ text box area. The file extensions must be entered
using the same syntax as the following example:
tif
aac
psd
6. Please note that all entries must be on a separate line. File extensions must
not have a ‘.’ (period) in front.
7. You can sort your list of custom content types alphabetically by clicking on the
‘Sort alphabetically’ option directly underneath the text area.
8. The ‘Set to Default’ button copies the settings from the Default Restriction,
making it easier and quicker to configure new filters.
9. Once you are satisfied with the content types you wish to filter on, click the
‘Save’ button located at the bottom of the screen. Clicking the ‘Cancel’ button
will return you to the previous page without saving any of the current settings.
To delete a Filter:
1. Click the ‘Web Filtering’ service tab on the main navigation bar at the top of
the screen.
2. On the Management sub-menu click the ‘Filters’. This will bring up the main
‘Filters’ page.
3. The main ‘Filters’ page presents you with a listing of all your current filters. In
order to delete one of these, click the ‘Delete’ icon located to the right of the
desired filter.
4. A dialog box will appear asking if you are sure you want to delete the filter.
Click the ‘OK’ button to proceed with deletion. The deleted filter will no longer
be displayed in the list on the main ‘Filters’ page.
If the filter you have chosen to delete has one or more pairings associated with it
in the Policy rules, then the web security service will not let you delete it. You must
first delete the dependent policy rule, then delete the filter.
