Regex Url Authorization Module
A web module that provides authorization based on urls matching regular expressions.
When to use it
When you need to authorize requests matching a regular expression. For instance you might want only registered users downloading any pdf files. Another idea might be to only allow administrators to view jpg files.
It uses standard .net web configuration for rules to specify authorization. So this means you can apply authorization per users or roles, and can be based on allow or deny rules.
The only think that has changed is the parent configuration node Location. It has been replaced with urlMatch, which matches a request based on a regular expression.
Url Match Element
- string Name - the unique name of the configuration element.
- string Expression - the regular expression, the incoming request must match, for authorization to be applied against it.
- AuthorizationRuleCollection Rules - the rules to apply. See http://msdn.microsoft.com/en-us/library/8d82143t.aspx for more information.
