I'm trying to add map services using the proxy, but nothing I do will work. We've tried calling ESRI support, but they told us that they don't support proxy. Which seems silly, seeing as how it's a feature in an ESRI product I'm trying to get help on, not an external proxy...
According to Fiddler, the proxy page is actually working. I followed ESRI's online instructions to configure it, and to point to the proxy.ashx within the builder. When I click the 'use proxy' box and try to browse to the server, I get an error that says "Cannot connect to <ourservername>." In fiddler it shows that it actually is trying to pass the urls, but it gives me this error:
Server Error
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
So it seems like it is able to access something. But in the Builder, it just says it can't connect.
Anyone? Help? I'm starting to pull out my hair here!
