Projects / Hydra


Hydra is a high performance multi-threaded HTTP server. Unlike traditional multi-threaded Web servers, it uses a constant, configurable pool of threads, and each thread can handle several connections by multiplexing the connections. This is even better than non-blocking servers, since Hydra will use every available CPU in a multi-CPU system. It also has features such as host-based virtual hosting, HTTP 1.1 features, CGI 1.1, SSL 3.0, TLS 1.0, and more. Hydra was based on the Boa Web server.
