The Servlet API for Perl (libservlet) is a formulation of the Java Servlet API in Perl. By writing servlet applications and deploying them in a servlet container, application authors can spare themselves the effort of writing commonly-needed Web application infrastructure components for each new project. Furthermore, servlet applications are portable between deployment environments; they can be executed in any servlet container using any process model with only a few configuration changes and no application code changes. Servlet applications are insulated from changes in vendor or platform and are able to portably take advantage of standard web infrastructure services offered by any servlet container.
Wombat is a Perl library that provides a servlet container implementing an adaptation of the Java (tm) Servlet API Specification for Perl. The engine gives application developers access to common Web infrastructure services in a manner that is independent of the deployment environment.
