Re: check wallet garden / internet connection

Something like this http://stackoverflow.com/questions/13958614/how-to-check-for-unrestricted-internet-access-captive-portal-detection in GWT would be nice!

Yes RequestBuilder is not working. The response-code there is always = 0 (same origin policy). 

Today I use as workaround JsonpRequestBuilder and try to receive JavaScriptObjects from "http://gdata.youtube.com/feeds/api/videos?". But there must be a better way to handle this. 

E.g. I want to test a walled garden URL like "http://clients3.google.com/generate_204" and others to be really sure that the client is inside a walled garden.

1) Walled Garden
2) Any attempt to contact a different server in the javascript will trigger a security warning in most browsers, if not be blocked.  You certainly can try and perform an HTTP request via RequestBuilder, but I wouldn't count on it being reliable.

I need to check if my GWT application is inside a wallet garden (wifi hotspot without internet connection). How to handle this in an easy way on client side?

Is there a way to ping e.g. google.com and return true/false in a method like "boolean isInWalletGarden();" ? Can anyone post such a method?
