Do any of you have a public / external facing app that is using the proxy? If so, in general terms, how did you configure it for this? For example, I have an app deployed on IIS that I access internally using http://gisserver/webapp and it uses the proxy at http://gisserver/DotNet/proxy.ashx. But I'm trying to make it available at something like http://www.webapp.mydomain.com and I'm having some trouble with including the proxy in the mix.
I got some help from Esri that I am working on, but I was hoping to get any advice from somebody with practical experience with this.
