Question

How do I handle the scenario where I making a synchronous request to the server using XMLHttpRequest and the server is not available?

xmlhttp.open('POST','Page.aspx',false); xmlhttp.send(null); 

Right now this scenario results into a JavaScript error: ‘The system cannot locate the resource specified’

Answer 1

Ok I resolved it by using try…catch around xmlhttprequest.send

:

xmlhttp.open('POST','Page.aspx',false);                      try        {        xmlhttp.send(null);        }        catch(e)        {             alert('there was a problem communicating with the server');        }
