No, that is for something different.  You probably want that set to  
true.

The best solution is probably to make your application able to handle  
double clicking.  One way to do this is to set a flag when the first  
click is detected and then just return the next page (or the current  
page) if a second click happens.

JavaScript like this might work:

onclick = "this.submit(); this.disabled=true;"
