slowcgi is a server which implements the FastCGI Protocol to execute CGI scripts. FastCGI was designed to overcome the CGI protocol's scalability and resource sharing limitations. While CGI scripts need to be forked for every request, FastCGI scripts can be kept running and handle many HTTP requests.
slowcgi is a simple server that translates FastCGI requests to the CGI protocol. It executes the requested CGI script and translates its output back to the FastCGI protocol.
