QueryTask and proxy problem -

JayGregory — Sun, 06 May 2012 18:17:57 GMT

I've constructed a query task that returns the number of points in a polygon.
This query task works perfectly if the query is against an internal map service (map service on the same arcgis server as the proxy).
However, if I set the query task to an external map service:

queryTaskWithin = new esri.tasks.QueryTask("http://rmgsc.cr.usgs.gov/ArcGIS/rest/services/nhss_haz/MapServer/0");

but change nothing else about the query or query task, it fails with the following error:

Error: Unable to load /proxy/proxy.ashx?http://rmgsc.cr.usgs.gov/ArcGIS/rest/services/nhss_haz/MapServer/0/query status:403

My proxy config shouldn't be the problem because - as I am on a test server, I've made it wide open, by setting ProxyConfig mustMatch="false". I didn't even need to include my internal map service in the proxy.config, and the query worked fine for that.

Any ideas what could be going on?

Thanks, Jay

What I understand from your description, place this http://services.arcgisonline.com/clientaccesspolicy.xml xml file in root directory of your server. Also place http://services.arcgisonline.com/crossdomain.xml this xml file in your servers root directory.

What I mean from server's root directory is the same directory where you placed your proxy.

These XML's help in granting access to request's coming from other domains to your server.

Thanks for your help - sorry for not responding earlier. I actually got around my issue by applying a layer definition. The information I needed to filter by was contained in the title string (state).
Thanks!
