## Web: PLT Web Applications

Jay McCarthy

This manual describes the PLT libraries for building Web applications.

Running Web Servlets describes how to run the servlets you’ve written.

Stateful Servlets and Stateless Servlets describe two ways to write Web applications. Stateful Servlets use the entire PLT Scheme language, but their continuations are stored in the Web server’s memory. Stateless Servlets use a slightly restricted PLT Scheme language, but their continuation can be stored by the Web client or on a Web server’s disk. If you can, you want to use Stateless Servlets for the improved scalability.

The HTTP: Hypertext Transfer Protocol section describes the common library function for manipulating HTTP requests and creating HTTP responses. In particular, this section covers cookies, authentication, and request bindings.

The final three sections (URL-Based Dispatch, Formlets: Functional Form Abstraction, and Templates: Separation of View) cover utility libraries that ease the creation of typical Web applications.

This manual closes with a frequently asked questions section: Troubleshooting and Tips.
