Insert custom http header into request

NathanielOlson

I have implemented a proxy in front of my arcgis server. The proxy has its own authentication that requires a custom http header be added to the http request. I have looked at the esriRequest.setRequestPreCallback to try set the headers there, but the ioArgs do not allow me to insert a custom header. Is there a way to insert a custom http header on all esri requests that go through my proxy?

I have seen this work :

esriRequest.setRequestPreCallback(function (ioArgs){

                                    if (ioArgs.url.indexOf("api2t.test.org") > -1) {

                ioArgs.headers = ioArgs.headers || {}; // make sure headers are not null

                                                ioArgs.headers["user_key"] = "zcc123thgkjdkfjksdf123jdsj5msd59" // add custom headers

                

                }

               return ioArgs;
