摘要
In accordance with an embodiment, described herein is a system and method for supporting the coexistence of an asynchronous architecture and a synchronous architecture in a same server. An async-enabled request acceptor and an async-disabled request acceptor can be configured in the server. The async-enabled request acceptor can direct connections to a keep-alive subsystem, where the connections can be serviced in an asynchronous fashion. The async-disabled request acceptor can direct connections to a request processing subsystem where the connections are serviced in a synchronous fashion. The system can include a user-level context switching API that enables each thread in the keep-alive subsystem to manage multiple connections simultaneously. The thread context for a connection can be executed until an I/O block is detected, at which point the thread context can be swapped out and the thread context of another ready connection can be swapped in.
