This is the main interface exposed by an asynchronous pluggable protocol. This interface and the IInternetProtocolSink interface communicate with each other very closely during download operations. 这是被同步可插拔协议暴露的主要接口，该接口在下载操作期间，和IInternetProtocolSink接口频繁交互。

LockRequest locks the requested resource so that the IInternetProtocolRoot::Terminate method can be called and the remaining data can be read.

The following table shows this interface's methods.

Method	Description
IInternetProtocol::LockRequest	Locks the requested resource.
IInternetProtocol::Read	Reads data retrieved by the pluggable protocol handler.
IInternetProtocol::Seek	Moves the current seek offset.
IInternetProtocol::UnlockRequest	Frees any resources associated with a lock.
