This is deprecated now in favor of using the Document.URL property to access a Url object.

In version 1.0 of JavaScript this was a simple string primitive value that contained the actual location of a window. It was not necessarily the same value as the Window.location.href value which always contained the requested location.

As of version 1.1 of JavaScript, this is now a reference to the same object that Window.location points at. However at the same time its use became deprecated.

Warnings:

• This location property is not the same as the location property that belongs to a window. The document.location property is a string containing the URL that the document was loaded from. The window.location property is a reference to the requested URL encapsulated in an object. Because of this, the document.location property is not preferred and you should use the document.URL property to avoid confusion.

• This property is supposed to be read only. However, Netscape 4 allows this property value to be changed. This is not recommended practice and you should use the Window.location.href property to change the page in the window.
