Limiting proxy use

BethBrennan — Tue, 08 Jan 2013 18:28:22 GMT

I have a website that allows users to add map services. If the map service is within a specified domain, I want it to use the proxy and if it is not, I want it to call the service directly. The services on the specified domain are secured and the proxy is used to request it with the correct credentials. I have implemented this by setting alwaysUseProxy to true. I use esri.setRequestPreCallback and if the requested url is not in the specified domain, I remove the proxy's prefix from the url.

The problem is that when I add the service to the map, all tiles are requested through the proxy. Does anyone know of a work around for this? My proxy will be on a server that will only have access to the specified domain. Thank you.

Here is what I am using:

esri.config.defaults.io.proxyUrl = "../../proxy.ashx";
              esri.config.defaults.io.alwaysUseProxy = true;
            esri.setRequestPreCallback(function(ioArgs) {
              if(ioArgs.url.toLowerCase().search(".bar.com") == -1 ) {

                ioArgs.url = ioArgs.url.replace("../../proxy.ashx?", "");
              }
              return ioArgs;
            });

I tried this on our Windows Authenticated services.

It worked for "reads"

But it is failing for feature layer updates. I'm getting a 401 when trying to do feature layer updates (looks like POST).
