Getting esri.config.defaults.io.proxyUrl is not set error when running on IE9

EdwardSohn2 · ‎01-07-2015

Getting esri.config.defaults.io.proxyUrl is not set error when running on IE9.

It does not happen with IE10, IE11, nor chrome.

EdwardSohn2 · ‎01-07-2015

It happens just before the authentication popup dialog should appear.

Full error:

Error: esri.config.defaults.io.proxyUrl is not set. If making a request to a CORS enabled server, please push the domain into esri.config.defaults.io.corsEnabledServers.

This is because IE9 doesn't support Cross-Origin Resource Sharing (CORS). You can see the support for CORS across various browsers here: http://caniuse.com/#feat=cors

To resolve this error you'll need to setup a proxy and and then set the proxy url in your application using esri.config.defaults.io.proxyUrl.

Details on how to install and setup the proxy can be found here: Esri/resource-proxy · GitHub

Did you test the proxy as described in the instructions section of this doc? resource-proxy/README.md at master · Esri/resource-proxy · GitHub

EdwardSohn2 · ‎01-12-2015

Got proxy (.Net) version set up.

Added Access-Control-Allow-Origin, *

to the Http Response Headers for the proxy site.

Without it was getting Access-Control-Allow-Origin not found error for the webmap website that was calling the proxy web server.

But with the

Access-Control-Allow-Origin, *

getting a different set of errors:

Multiple Access-Control-Allow-Origin headers are not allowed for CORS response

Not defining Access-Control-Allow-Origin anywhere else in the webmap. What's the best way to remove these errors or setup the Access-Control-Allow-Origin on the proxy webserver to avoid either the Access-Control-Allow-Origin error or the Multiple Access-Control-Allow-Origin headers error?
