1.) If the domain of the external URL is actually your production domain (the one where you would deploy and access the app for production) but you are developing using localhost as domain or similar, you can disable SOP in several browsers (google for "disable SOP"). But this is only useful for developing.
2.) Make a request from GWT client to your GWT server and your GWT server makes a request to the external URL. 3.) Use a reverse proxy where you can map any external URLs to URLs of your domain, e.g. a GWT client request to http://www.yourdomain.com/external/mydata may be redirected by the reverse proxy to http://www.mydata.com/api. -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
