SPServer is a high concurrency C++ server framework library that implements the Half-Sync/Half-Async and the Leader/Follower thread pool patterns. It is based on libevent (Unix/Linux) and IOCP (Win32) in order to utilize the best I/O loop on any platform. It supports SSL for secure transactions. An SSL proxy, sptunnel, is included along with an embedded HTTP server framework, sphttp.
Tdbengine is an RDBMS with an integrated programming language. It represents the enhancement of the famous DOS-TDB, and is designed to handle databases on the Web. It connects to the Web server using the standard CGI interface, or runs on the command line. It is very small (about 400 KBytes), extremely quick, and easy to administrate. Its features are full text indexing, an automatic data link system, and the script language EASY, which replaces the commonly used SQL with its modular code.
teepeedee is a small, fast, single-threaded file server. It is very scalable, and can serve multiple files over HTTPS, HTTP and FTP simultaneously, listening on any number of ports and providing entirely different views of the filesystem to different users. It supports most of the draft-ietf-ftpext-mlst-16.txt FTP extensions, as well as EPRT, EPSV, AUTH TLS, and HTTP 1.1 persistent connections.
Tomkitty is a Web server written in Java. It was conceived initially as a container for Web applications called Turdlets, themselves conceived as a simple alternative to Servlets. The code, though badly documented, has been put together with simplicity and understandability in mind and uses interfaces extensively. The general idea is a clean, stable, and scalable Web server in Java without the complexity and steep learning curve that comes with running the whole Tomcat system.
trapdoor2 allows remote users to execute local commands by sending 'magic cookies'. this can e.g. be used to alter local firewalling rules so people can connect to local services after sending the magic cookie. trapdoor2 is implemented as a high-secure HTTPS server and includes support for the Wireless Application Protocol (WAP).
