Web systems for ANSI Common Lisp

I (David Owen) am interested in either finding or building a good web system for CL, and also codifying and standardizing that system. It must have clearly-separated components that each do their own job well, and allow substitution of other components. A good example is  Django for Python, explained by  Django's design philosophies.

My current focus is on TemplateComponents. I'm also thinking about Deployment.
