ProcHandler

WEBrick allows you to be lazy. If your need is trivial and can be expressed in a simple Proc or a block, then you don't have to bother with subclassing AbstractServlet.

start_webrick {|server|
  server.mount_proc('/myblock') {|req, resp| 
    resp.body = 'a block mounted at #{req.script_name}'
  }

  my_wonderful_proc = Proc.new {|req, resp|
    resp.body = 'my wonderful proc mounted at #{req.script_name}'
  }
  
  server.mount_proc('/myproc', my_wonderful_proc)

  server.mount('/myprochandler', 
    HTTPServlet::ProcHandler.new(my_wonderful_proc))
}

Output:

dede:~$ w3m -dump http://localhost:8080/myblock
a block mounted at /myblock
dede:~$ w3m -dump http://localhost:8080/myproc
my wonderful proc mounted at /myproc
dede:~$ w3m -dump http://localhost:8080/myprochandler
my wonderful proc mounted at /myprochandler
