//MS Ajax isn't handling getstatus exception, so i have to insert my own try/catch
//I'm doing it by creating a new prototype method... instead of rewriting the whole 
//function, i'm simply taking the text of the current function, changing the name
//via replace, and changing the line accessing status to have try/catch wrapped around
//it.  If the status call errors out, i'm returning error 999.  You can return whatever you 
//want.
//PS.  I'm no javascript guru, so forgive me if I didn't use the most efficient
//code for creating a replacement function with the fixes.
//get the current function text
var funcText = Sys$Net$XMLHttpExecutor$get_statusCode.toString();
//our new function will have 'Patched_' appended to the start of the existing function
funcText = funcText.replace('Sys$Net$XMLHttpExecutor$get_statusCode', 'Patched_Sys$Net$XMLHttpExecutor$get_statusCode');
//replace status access with same line, except with try/catch block wrapped around it
funcText = funcText.replace('return this._xmlHttpRequest.status;', 'try {return this._xmlHttpRequest.status;} catch(e) {return 999;};');
//create new function using eval... to use funct = new Function or func = function() {...}, 
//I'd have to take the funcText and strip the function line and bracket from the beginning and the
//end.  I could have done it by removing the first and last lines, but I did it this way instead.

//have the prototype method point to the new function instead of the old one
