About Asynchronous Pluggable Protocols

Asynchronous pluggable protocols enable developers to create pluggable protocol handlers, MIME filters, and namespace handlers that work with Microsoft Internet Explorer 4.0 and later and a URL moniker. This article covers the pluggable protocol functionality exported by the Urlmon.dll DLL.

Debugging Tips

This article provides tips for handling exceptions and understanding HRESULT error codes generated by pluggable protocols.

Registering an Application to a URL Protocol

The About Asynchronous Pluggable Protocols article describes how to develop handlers for new protocols. In some cases, it may be desirable to invoke another application to handle a custom protocol. To do so, register the existing application as a URL Protocol handler. Once the application has successfully launched, it can use command-line parameters to retrieve the URL that launched it.

Interfaces

IInternetProtocolEx

Exposes a method that communicates closely with the IInternetProtocolSink interface during download operations. This interface extends IInternetProtocol to add support for IUri

IInternetProtocolSinkStackable

Enables a pluggable MIME filter to be added to an existing filter at run time.
