The WA SET URL FILTERS command sets up one or more filters for the Web area designated by the * and object parameters.
Before loading any page requested by the user, 4D consults the list of filters in order to check whether or not the target URL is allowed. The evaluation of the URL is based on the contents of the filtersArr and allowDenyArr arrays.
If the requested URL is not allowed, it is not loaded and the On URL Filtering form event is generated.
The filtersArr and allowDenyArr arrays must be synchronized.
- Each element of the filtersArr array must contain a URL to be filtered. You can use the * as a wildcard to replace one or more characters.
- Each corresponding element in the allowDenyArr array must contain a Boolean indicating whether the URL must be allowed (True) or denied (False).
If there is a contradiction at the configuration level (the same URL is both allowed and denied), the last setting is the one taken into account.
To disable URL filtering, call the command and pass empty arrays or pass, respectively, the values "*" and True in the last elements of the filtersArr and allowDenyArr arrays.
Once the command has been executed, the filters become a property of the Web area. If the filtersArr and allowDenyArr arrays are deleted or reinitialized, the filters remain active as long as the command has not been executed again. To find out the active filters for an area, you must use the WA GET URL FILTERS command.
Important: The filtering of URLs carried out by this command only applies to the "URL" variable associated with the Web area (variable usually enterable and displayed in the form).
The filtering does not apply to the WA OPEN URL command, nor to the other navigation commands.

APPEND TO ARRAY($AllowDeny;False)
APPEND TO ARRAY($filters;"*.net")
APPEND TO ARRAY($AllowDeny;False)
APPEND TO ARRAY($filters;"*.fr")
APPEND TO ARRAY($AllowDeny;False)
WA SET URL FILTERS(MyWArea;$filters;$AllowDeny)You want to deny access for all Web sites except Russian ones (.ru):
