I deployed an app to a local server without access to the internet and I have all my resources local and referenced. However, when it's running, it auto-generates the following code
<script src="http://ajax.aspnetcdn.com/ajax/4.6/1/webForms.js" type="text/javascript"></script>
<script src="http://ajax.aspnetcdn.com/ajax/4.5.1/1/MicrosoftAjax.js" type="text/javascript"></script>
<script src="http://ajax.aspnetcdn.com/ajax/4.5.1/1/MicrosoftAjaxWebForms.js" type="text/javascript"></script>
I have said files locally but I don't know how to use them instead of the links.
Download the script files (webForms.js, MicrosoftAjax.js, MicrosoftAjaxWebForms.js) from the ASP.NET CDN Place them in a suitable folder within your application's directory structure, such as a "Scripts" or "Resources" folder.
Ensure the paths are correct relative to the location of your ASPX pages.
