Xtiny is a light but high performant concurrent webserver

xtiny

XTiny is a high performance concurrent server written for Internet Services course at CMU. http://www.ece.cmu.edu/~ece845/

Design:

A request is accepted and its execution is deffered to a thread pool. A thread picks up the request from the thread pool queue, serves the request and closes the connection. Note that only HTTP 1.0 is supported (No persistent connection support).

Static requests are served my mmap'ing the static file.

Dynamic Requests: CGI - As the CGI protocol mandates, each cgi request is handled by forking a process and dup'ing the standard out.

Snap: In the snap mode dynamic requests are handled by a separate process. A thread from the threadpool offloads the dynamic serving to another process using UNIX Domain Sockets by passing the connection descriptor and the HTTP arguments to the dynamic serving process. The dynamic request serving process can form the response and write it to the passed connection descriptor and close the request.

Starting: ./xtiny -p 8000 -f settings.conf -q 50 -t 50 -d /tmp/domain.sock (q is the queue size and t is the number of threads in the thread pool)

Start the dynamic serving process using ./content /tmp/domain.sock
