Urlmon.dll is part of Microsoft Internet Explorer and offers functionality for MIME handling and code download. Internet Explorer uses two mechanisms for registering new URL protocol handlers. The first method is to register a URL protocol and its associated application so that all attempts to navigate to a URL using that protocol launch the application (for example, registering applications to handle mailto: or news: URLs). The second method uses the Asynchronous Pluggable Protocols API, which

“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. Applications can use pluggable protocol handlers to handle a custom Uniform Resource Locator (URL) protocol scheme or filter data for a designated MIME type. The ability to handle a custom URL protocol scheme using a pluggable protocol handler allows developers to implement new or custom protocol”
