Rails - Nov 2010 - Rails and JQuery and Ajax/Json question

Hi,

I am using JQuery in my rails app.  I''ve taken the approach outlined
in Ryan Bates''s Railscast on jquery to do the following:

jQuery.ajaxSetup({
    ''beforeSend'' : function(xhr)
{xhr.setRequestHeader("Accept",
"text/javascript")}
});

to set my ajax call request Headers to text/javascript so that my
respond to block for javascript is invoked.

This works great up until I get to wanting to call jQuery.getJSON

It appears that my ajaxSetup call causes the getJSON call to send the
text/javascript header instead of application/json.

Now there are a number of ways I can work around this (using
jQuery.ajax, not using ajaxSetup ...)

But I was wondering if there is a convention that folks have adopted
in cases like this?

Thanks!
Jay
