When a script reference is rendered, the ScriptReferenceEventArgs object contains the ScriptReference object that is defined in the ScriptManager instance. You can create an event handler for the ResolveScriptReference event to check the ScriptReference object and modify it as needed.
The following example shows an ASP.NET Web page that references a script file that is named CustomScript.js. When the Web application is hosted on the www.contoso.com domain, the Path property is set to a value specific for that domain. An event handler for the ResolveScriptReference event checks the host URL and changes the value for the Path property if it is necessary.
