KLone - Embedded Web Server and SDK

KLone is a fully-featured, multiplatform, web application development framework, targeted especially for embedded systems and appliances. It is a self-contained solution which includes a web server and an SDK for creating WWW sites with both static and dynamic content. When using KLone, there's absolutely no need for any additional component: neither the HTTP/S server (e.g. Apache, Netscape, Roxen), nor the typical active pages engine (PHP, Perl, ASP, Python). KLone does everything, and does it fast and small. KLone blends the HTTP/S server application together with its content and configuration into a single executable file. The site developer writes his/her dynamic pages in C/C++ (in usual scripting style: <% /* code */ %>) and uses KLone to transform them into embeddable, compressed native code with the native C/C++ compiler. The result is then linked to the HTTP/S server skeleton to obtain one single, ROM-able, binary file.

They don't call it "C server pages", but that's what it is.
