HTTPit Web Server

HTTPit is a tiny multi-threaded executable java based HTTP server (under 10kb). It was built as a simple challenge to myself, how much functionality could be coded into a .jar file under 10Kb in size. It supports SSI and CGI (to the point that PHP applications function correctly) and supports both GET and POST request, 52 document types, virtual hosting ….

:. System Requirements

This server uses the regular expressions support added in JDK1.4.x and therefore requires that version as a minimum.
