### Instantiate an Html place with the name receive and port 8090
HtmlPlace ::receiver -port 8090 -allowExit exit

### Define a class Counter as a special Html Document
Class Counter -superclass HtmlDocument -parameter {{count 0}}

Counter instproc init args {       ;### Constructor
  next
  my persistent count              ;### make count variable persistent
  ::receiver exportObjs [self]     ;### export the counter object
  my exportProcs increment         ;### export counter's  increment method
}
Counter instproc default {} {     ;### Method for updating HTML page
  set objName [string trimleft [self] :]
  return "The value in $objName is now: [my set count].<p>
	Increment Counter<p>
	
Last Update: [clock format [clock seconds]]
	\n"
}
Counter instproc increment {} {    ;### exported increment method
  my incr count
  return [my default]
}

### Create two counter instances with the names
### counter-1.html and counter-2.html 
Counter counter-1.html
Counter counter-2.html

### Start event loop and handle connections
receiver startEventLoop
