//
// Description; basic AJAX framework for ASP.NET projects
//
// Usage:
// Implement two functions to handle successfull and failed requests.
// In your page create an instance of responseHandler(fnSuccess, fnFail)
// passing references to the above functions in the constructor.
// call the executeRequester(method, url, cgi, myHandler) function,
//
// Examples:
// function mySuccessHandler(requester){ alert(requester.responseText); }
// function myFailedHandler(requester){ alert("Request failed!"); }
//
// var myHandler = new responseHandler(mySuccessHandler, myFailedHandler)
//
// executeRequester("GET", "YourPage.aspx", "", myHandler);
// executeRequester("GET", "YourPage.aspx", "ID=1&value=value", myHandler);
// executeRequester("POST", "YourPage.aspx", "ID=1&value=value", myHandler);
//
// Compatability:
// IE 6, Firefox 1.5, (opera, safari, etc. should work but not tested)
//
