/***************************************************************************­********** 
USAGE 
  ahah("processer.php?var1=xxx&var2=yyy","mydiv"); 
or: 
  ahah("processer.php?var1=xxx&var2=yyy", undefined, "myfunction"); 

This second one is very useful if you need to pass the processed data 
into a function: 
function myfunction(my_processer_response){ 
  ....
