8.2 No Continuations

 (require web-server/managers/none)

"managers/none.ss" defines a manager constructor:

(create-none-manager instance-expiration-handler)  manager?

  instance-expiration-handler : expiration-handler?

This manager does not actually store any continuation or instance data. You could use it if you know your servlet does not use the continuation capturing functions and want the server to not allocate meta-data structures for each instance.

If you are considering using this manager, also consider using the Web Language. (See Web Language Servlets.)
