- the implementation is inspired by Jetty's DefaultServlet - handles static html content and YaCy servlets - translates between standard servlet request/response and YaCy request/response specification With the implementation of YaCy-servlets as servlet instead via a jetty handler it's closer to servlet standard and carries less jetty specific dependencies.
