Child Elements


Parent Elements

Element Description
webRequestModules Specifies modules to use to request information from network hosts.


The prefix attribute defines the URI prefix that uses the specified Web request module. Web request modules are typically registered to handle a specific protocol, such as HTTP or FTP, but can be registered to handle a request to a specific server or path on a server.

The Web request module is created when a URI matching prefix is passed to the WebRequest.Create method.

The value for the prefix attribute should be the leading characters of a valid URI. For example, http or http://www.contoso.com.

The value for the type attribute should be a valid type name and corresponding assembly name, separated by a comma.

Configuration Files

This element can be used in the application configuration file or the machine configuration file (Machine.config).
