What is exact use of clientglobalcontext.js.aspx in Dynamics CRM?

Question

In sample example in SDK and at different places on internet Clientglobalcontext.js.aspx file is mentioned, if I do not include it in my html web resource, it throws exception, but if I include file like,

<script src="ClientGlobalContext.js.aspx" type="text/javascript"></script>

Then only rest endpoint API is working. Now, I am not able to locate this file anywhere. What is exact use of this file? How to locate it?

Answer 1

The purpose of the ClientGlobalContext.js.aspx is to provide the GetGlobalContext function.

It's all explained inside MSDN:

GetGlobalContext function and ClientGlobalContext.js.aspx (client-side reference)

The GetGlobalContext function returns the same context object found in the Xrm.Page.context.

The file is generated server-side, practically the ClientGlobalContext.js.aspx push a JavaScript file to the client when it is included with the <script> tag syntax.
