Winsock LSP (Layer Service Provider) Facts And Issues
Virtually all network applications employ Winsock to communicate over the Windows network. This process of communication is multi-stepped. Beginning with Winsock API calls, they are redirected a number of time before finally reaching the kernel. At that level, NDIS technology routes the calls. A Winsock Layered Service Provider, otherwise known as Winsock LSP is a kind of technology that allows the user to place code between Winsock API and the end users network calls.
