Re: how to test GWT app through a proxy

I don't think it's directly related to the proxy pattern that Dan mentioned.  It seems to be that your user doesn't have great internet access, or there is some issue in the connection between that user and your web server.  It seems that the error message happens when the browser is not able to communicate (reliably) with the web server.

Here is a related link that could help you out:  http://stackoverflow.com/questions/5258434/unable-to-initiate-the-asynchronous-service-invocation

GWT must be writing the "MyDataService_Proxy" part.

And then there is this one (thankfully) very vocal
user, whose access to the RPC needed by the application
goes through the "MyDataService_Proxy" part,
and it works for him only occasionally.

I would like to be able to test the "MyDataService_Proxy"
part from where I am developing, or at least from
somewhere nearby.
