Web Filter: Exception

Time Profile > Exception:

Exception URL
The Exception tab is used for allowing users to be blocked from accessing specified URLs and/or to be allowed to access specified URLs blocked at the minimum filtering level.

NOTE: Settings in this window work in conjunction with those made in the Override Account window and in the Minimum Filtering Level window maintained by the global administrator. IP group users with an override account will be able to access URLs set up to be blocked in this window, if the global administrator activates bypass settings in the Minimum Filtering Bypass Options tab.

A URL can contain a domain name such as http://www.yahoo.com or an IP address such as http://216.109.118.77/. The asterisk (*) wildcard and period (.) can be used in the URL entry. For example: *.yahoo.com will block all URLs containing the text following the period and asterisk. A minimum of three wildcard levels can be entered (e.g. *.yahoo.com), up to a maximum of six wildcard levels, (e.g. *.mail.attachments.message.yahoo.com).

The following types of URL formats also can be entered in this window:
• octal format - e.g. http://0106.0125.0226.0322
• hexadecimal short format - e.g. http://0x465596d2
• hexadecimal long format - e.g. http://0x46.0x55.0x96.0xd2
• decimal value format - e.g. http://1180014290
• escaped hexadecimal format - e.g. http://
%57%57%57.%41%44%44%49%43%54%49%4E%47%47%41%4D
%45%53.%43%4F%4D
• query string format - e.g. http://www.youtube.com/watch?=v=3_Wfnj1llMU
• case-specific entries - these entries are used by the YouTube Video Control feature that blocks or allows end user accessibility to specific YouTube video URLs

Add URLs to Block URL or ByPass URL frame
1. Type the URL to be blocked in the Block URLs field, or the URL to be bypassed in the ByPass URLs field.

2. Click Add to open the Add Block URLs / Add Bypass URLs pop-up window to view all corresponding URLs found by the query, with a pre-populated checkbox preceding each URL entry in the table.

NOTE: If any conflicts are found between URLs from the current query and ones previously saved in the Exception URL window, the Status column in the pop-up window displays an icon with a legend at the bottom of the window explaining the meaning of that symbol:
• URL can be added, but conflicting URLs will be removed (yellow triangle containing an exclamation point) - This pertains to any URL from the query that was found to be included in the opposite list (Block or Bypass).
• URL cannot be added due to conflicts (red circle with a line through it) - This pertains to any URL from the query that is already included in the same list (Block or Bypass). The URL cannot be added since it is already included in the list.

To proceed adding URLs, click the “Ignore warnings and add URL” checkbox which activates the Add Selected button.

3. If necessary, uncheck the Add checkbox preceding the URL listed in the table. Clicking the “Check/Uncheck All 'Add'” checkbox at the bottom of this window toggles between selecting or de-selecting all checkboxes in this window.

4. If a multi-level URL was executed in the query, e.g. http://yahoo.com/mail, the Match case column contains an empty checkbox for each entry in the table. Check the checkbox corresponding to a URL entry you want to designate as being case-specific. The URL entry made by the end user must exactly match this entry in order for the URL to be blocked or bypassed, as set up in this window. Clicking the “Check/Uncheck All” checkbox at the bottom of this window toggles between selecting or de-selecting all Match case checkboxes in this window.

5. Click Add Selected to close the pop-up window and to add your selection(s) in the appropriate URL list box.

Remove URLs from Block URL or ByPass URL frame
1. Select a URL to be removed from the Block URL / ByPass URL list box; your selection populates the Block URLs field / ByPass URLs field.

TIP: Choose a non-IP address URL to maximize results to be returned by the URL query.

2. Click Remove to open the Remove Block URLs / Remove ByPass URLs pop-up window to view all corresponding URLs found by the query. This window includes a pre-populated checkbox preceding each URL found by the query. Uncheck any checkbox corresponding to a URL you do not want to remove from your list. Clicking the “Check/uncheck all” checkbox at the bottom of this window toggles between selecting or de-selecting all checkboxes in this window.

3. Click Remove Selected to close the pop-up window and to remove your selection(s) from the appropriate URL list box.
