Webresource.axd and Scriptresource.axd 404 not Found

Recently I faced a strange issue in the process of development using script manager for async post backs.

The error is "webresource.axd and scriptresource.axd 404 not found”. Whenever I do any async call I use to get this error "sys is not defined”. I have tried a lot to fix this issue by following the below links and so on....

After spending 4 hours I found a new property on asp.net 4.0 called EnableCdn that basically, if it's set to "true", it loads the resources from the Microsoft content resource servers.

Refer this link (http://msdn.microsoft.com/en-us/library/system.web.ui.scriptmanager.enablecdn (v=vs.100).aspx) for information about EnableCDN.

This worked like a charm and fixed my issue.
