SteelBlue is an Open Source Web application server similar to Cold Fusion. It extends HTML with tags to execute SQL commands, perform type checking on user input, loop over sections of code, and manipulate data. In addition, it has a Perl-like scripting language that can be embedded directly into the HTML for complex data manipulation. SteelBlue runs as a CGI script on Linux, UNIX variants (via gcc 2.8), and Win32. It includes native support for most popular relational databases and the embedded scripting language is extensible though a C++ API. Included in the distribution are a book about programming SteelBlue, many examples, and a full bulletin board application.
