How to implement "Access-Control-Allow-Origin" header in asp.net

Question

Is it possible to implement "Access-Control-Allow-Origin" header in asp.net

Answer 1

From enable-cors.org:

CORS on ASP.NET

If you don't have access to configure IIS, you can still add the header through ASP.NET by adding the following line to your source pages:

Response.AppendHeader("Access-Control-Allow-Origin", "*");

Answer 2

Another option is to add it on the web.config directly:

<system.webServer>     <httpProtocol>       <customHeaders>         <add name="Access-Control-Allow-Origin" value="http://www.yourSite.com" />         <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS"/>         <add name="Access-Control-Allow-Headers" value="Origin, X-Requested-With, Content-Type, Accept" />       </customHeaders>     </httpProtocol>
