I've been revisiting the cross-site request approaches (currently using JSONP) and tried to search the mailing list for this answer but didn't find it.

Is it possible to modify development mode to send an Access-Control-Allow-Origin header?

Er, I'm puzzled. If you use Dev Mode's embedded server to serve your data, then you don't hit the SOP, right? and thus you don't need CORS? Or have I missed something obvious?

That being said, you have several solutions:

• configure a servlet filter in your web.xml that adds the header to your responses (clearly the easiest solution)
• copy com.google.gwt.dev.shell.jetty.JettyLauncher and modify it to send the ACAO header, and pass the -server argument to DevMode to use your class.
