Yet another fast and efficient HTTP server.


The purpose of Zaver is to help developers understand how to write a high performance server based on epoll. Although Nginx is a good learning example, its complexity and huge code base make people discouraged. Zaver uses as few codes as possible to demonstrate the core structure of high performance server like Nginx. Developers can lay a solid foundation by learning Zaver for further study in network programming.

programming model

  • epoll
  • non-blocking I/O
  • thread-pool

compile and run (for now only support Linux2.6+)

please make sure you have cmake installed.

mkdir build && cd build
cmake .. && make
cd .. && ./build/zaver -c zaver.conf


  • HTTP persistent connection
  • browser cache
  • timer(use binary heap instead of rbtree used in Nginx)


  • add command line parameter
  • add conf file
  • sendfile
  • proxy
  • FastCGI
  • other HTTP/1.1 features
  • memory pool
  • WebDAV?
