Asynchronous Pluggable Protocols
Asynchronous pluggable protocols provide the capability to create custom URL protocols. This section covers the pluggable protocol functionality exported by the Urlmon.dll DLL.
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.

Windows Internet Explorer implements various protocols that can be used to identify certain information. A protocol is a set of rules and standards that enables two or more computers to communicate.
Registering an Application to a URL Protocol
The About Asynchronous Pluggable Protocols article describes how to develop handlers for URL 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. After the application has successfully launched, it can use command-line parameters to retrieve the URL that launched it. These settings apply to protocol handlers launched from within Internet Explorer and from Windows Explorer using the Run... command (Windows logo key+R).
Provides methods that are used to compress and uncompress data in a pluggable protocol.
Provides an implementation of the IUnknown interface, which enables client programs to determine if asynchronous pluggable protocols are supported. No additional methods are supported by this interface.
Implemented by the system; provides data that the protocol might require to bind successfully.
Extends IInternetBindInfo by providing additional data that the protocol might require.
Enables an application to set the priority of the requests that are sent to a pluggable protocol handler.
Exposed by an asynchronous pluggable protocol; communicates with the IInternetProtocolSink interface during download operations.
Exposes a method that communicates closely with the IInternetProtocolSink interface during download operations. This interface extends IInternetProtocol to add support for IUri
Provides information about the URL being handled by the protocol handler.
Controls the operation of an asynchronous pluggable protocol handler.
Receives the reports and binding data from the asynchronous pluggable protocol.
Enables a pluggable MIME filter to be added to an existing filter at run time.
Implemented by the client application to create temporary pluggable protocol handlers.
Notifies the protocol handler that the moniker is being switched from one UI thread to another.
Creates a session that allows temporary asynchronous pluggable protocols to be implemented and returns the IInternetSession interface of the session.
Contains state information about the protocol that is transparent to the transaction handler.
Contains the IInternetProtocolSink and IInternetProtocol interfaces of the application calling a pluggable MIME filter.
Contains the values for the bind string types available for IInternetBindInfo::GetBindString.
Contains the flags that control the asynchronous pluggable protocol handler.
