title: What is .jspa URL extension in web applications?
body: <p>In many online web applications, I notice that the application url ends with jspa. My assumption is it is a jsp and action is mapped to jspa instead of *.do.</p>
  
  <p>Is my understanding correct or there is an actual extension/different meaning? Kindly suggest and  ignore if this question is very basic. I googled already and could not get clear answer. </p>
