10.2 URL Rules
143
Valid at time interval
Selection of the time interval during which the rule will be valid (apart from this
interval the rule will be ignored). Use the Edit button to edit time intervals (for
details see chapter 12.2).
Valid for IP address group
Selection of IP address group on which the rule will be applied. Client (source)
addresses are considered. Use the Any option to make the rule independent of
clients.
Click on the Edit button to edit IP groups (for details see chapter 12.1).
Valid if MIME type is
The rule will be valid for a certain MIME type only (for example, text/html — HTML
documents, image/jpeg — images in the JPEG format, etc.).
You can either select one of the predefined MIME types or define a new one. An
asterisk substitutes any subtype (i.e. image/
*
). An asterisk stands for any MIME
type — the rule will be independent of the MIME type.
Denial options
Advanced options for denied pages. Whenever a user attempts to open a page that
is denied by the rule, WinRoute will display:
• a page informing the user that access to the required page is denied as it is
blocked by the firewall. This page can also include an explanation of the denial
(the Denial text item).
The Unlock button will be displayed in the page informing about the denial if the
Users can Unlock this rule is ticked. Using this button users can force WinRoute
to open the required page even though this site is denied by a URL rule. The
page will be opened for 10 minutes. Each user can unlock a limited number of
denied pages (up to 10 pages at once). All unlocked pages are logged in the Filter
log (see chapter
20.9).
Notes:
1. Only subscribed users are allowed to unlock rules.
2. If any modifications are done within URL rules, all unlock rules are removed
immediately.
• a blank page — user will not be informed why access to the required page was
denied.
• another page — user’s browser will be redirected to the specified URL. This op-
tion can be helpful for example to define a custom page with a warning that
access to the particular page is denied.
