How to extend jquery jqXHR object

Can we add additional methods to jqXHR object? I had a app built using prototype.js which was extending the response

Ajax.Response.addMethods({});

What is the equivalent for Jquery?

I want to add few methods that are specific to my app. For example, I want to add a method 

getMyHeader: function(name)
{
     return this.getResponseHeader('MY-'+name);
}

which returns me a specific header sent by server.

It doesn't look like jQuery specifically supports this. The jqXHR object they create is just a generic object with methods added as properties so there isn't a prototype you can modify and I don't see any jQuery methods for modifying it.

The only work-around I could see was to register a handler for a global ajax event like jQuery.ajaxSend() and add the desired methods to each specific jqXHR object in that global handler. Then, those methods would be available later.
