Barracuda supports a very advanced type of server side scripting, which we call CSP. CSP is similar to Active Server Pages, ASP, which was invented by Microsoft. With CSP, you can embed C or C++ directly into an HTML template page created by an HTML designer.
Please see our CSP tag language white paper for more information on how to design and do rapid development of advanced device control logic using the CSP compiler.
