jQuery.extend(deep) not working?

[Adam Nelson-2]

I'm trying out this need extension:

http://binarykitten.jkrswebsolutions.co.uk/2009/01/21/jquery-plugin-ajax-head-request/comment-page-1

which allows jQuery to do a HEAD request on an arbitrary URL in order
to grab header values for a given page.  Unfortunately, if that page
is the page the script is currently running from, it goes into an
infinite loop which results in:

[Exception... "Component returned failure code: 0x80004001
(NS_ERROR_NOT_IMPLEMENTED) [nsIDOMLocation.host]" nsresult:
"0x80004001 (NS_ERROR_NOT_IMPLEMENTED)" location: "JS frame ::
http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js ::
anonymous :: line 12" data: no]
[Break on this error] (function(){var l=this,g,y=l.jQuery,p=l.....each
(function(){o.dequeue(this,E)})}});

If I add deep to jQuery.extend(), I get "deep is not defined".

Does anybody have any help for this?  Should the code be refactored to
not extend but to be a more simplistic?

jQuery 1.3.2

I have endless circle in like this code:

$(function ()
{
 $.getJSON("http://foo.com/json/?callback=?", {ref: document.referrer,
loc: window.location});
});

This code is second ready() callback. If i remove this code from my
scripts, all works fine
If i add, i have endless circle in browser (firefox 3.0.11) and i see
a following errors not minimised jquery version:

Error: [Exception... "Component returned failure code: 0x80004001
(NS_ERROR_NOT_IMPLEMENTED) [nsIDOMLocation.host]"  nsresult:
"0x80004001 (NS_ERROR_NOT_IMPLEMENTED)"  location: "JS frame ::
http://mysite-url-here.com/js/jquery-1.3.2.js :: anonymous :: line
604"  data: no]
Source File: http://mysite-url-here.com/js/jquery-1.3.2.js
Line: 604

I think that this very bad bug because it causes endless circle of
loading at serfer side ...

I found my trouble

jQuery serializes the document.referrer & window.location as Object()
with properties
I resolved this by:

$.getJSON("http://foo.com/json/?callback=?", {ref: String
(document.referrer),
loc: String(window.location)});
