Hi, I'm having problems to set the proxy for my application! My current setup: - ArcGIS Server 10.4 on 'server.virtual.private' or '192.168.210.100' - Proxy .NET running with IIS 8.5 on 'server.virtual.private' (same machine than ArcGIS Server 10.4) - Application with Javascript API 3.16 on 'host-vm' or '192.168.210.1' (with browsersync.io) Installed the proxy from GitHub Put the .NET version on a inetpub\wwwroot subfolder, created a app, etc... Then, I tested the proxy (according with the README.md): "Test that the proxy is installed and available": http://server.virtual.private/DotNet/proxy.ashx?ping! Got a valid response: { "Proxy Version": "1.1.0", "Configuration File": "OK", "Log File": "Not Exist/Readable"} "Test that the proxy is able to forward requests directly in the browser using": http://server.virtual.private/esri_proxy/proxy.ashx?http://server.virtual.private/arcgis/rest/services/teste/TEST_SERVICE/FeatureServer?f=json Got a valid response: {    "currentVersion":10.4,    "serviceDescription":"TEST_SERVICE",    "hasVersionedData":false,    "supportsDisconnectedEditing":false,    "syncEnabled":false,    "supportedQueryFormats":"JSON, AMF",    "maxRecordCount":1000,    "capabilities":"Create,Delete,Query,Update,Uploads,Editing",    "description":"",    "copyrightText":"",    "spatialReference":{       "wkid":102100,       "latestWkid":3857    },    "initialExtent":{       "xmin":-5373925.95008382,       "ymin":-1779327.897638279,       "xmax":-5367538.895643042,       "ymax":-1776174.0579972658,       "spatialReference":{          "wkid":102100,          "latestWkid":3857       }    },    "fullExtent":{       "xmin":-5371483.1645,       "ymin":-1779695.3658000007,       "xmax":-5368931.5394,       "ymax":-1776737.2322000004,       "spatialReference":{          "wkid":102100,          "latestWkid":3857       }    },    "allowGeometryUpdates":true,    "supportsApplyEditsWithGlobalIds":false,    "units":"esriMeters",    "documentInfo":{       "Title":"",       "Author":"",       "Comments":"",       "Subject":"",       "Category":"",       "Keywords":"TEST_SERVICE"    },    "layers":[       {          "id":0,          "name":"TEST_SERVICE"       }    ],    "tables":[    ],    "enableZDefaults":false } So, the proxy appear to be OK! Then, I edited the proxy.config file, with this content (this is for test development): <?xml version="1.0" encoding="utf-8" ?> <ProxyConfig allowedReferers="*" mustMatch="false">   <serverUrls>       <serverUrl url="http://server.virtual.private" matchAll="true" username="siteadmin" password="secret" />   </serverUrls> </ProxyConfig> Then, according with README.md​, and document on Using the proxy | Guide | ArcGIS API for JavaScript I must put the URL of the proxy on my javascript application. I put the following lines on top of main file of application: esriConfig.defaults.io.proxyUrl = 'http://server.virtual.private/DotNet/proxy.ashx'; esriConfig.defaults.io.alwaysUseProxy = false; Tested my application and got a 500 response when asked for a Feature Layer. "XMLHttpRequest cannot load http://server.virtual.private/DotNetProxy/proxy.ashx?http://server.virtual.private/arcgis/rest/services/teste/TEST_SERVICE/FeatureServer?f=json. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested source. Origin 'http://192.168.210.1:8080' is therefore not allowed access.". So, I got a CORS! but according with the documentation on Using the proxy | Guide | ArcGIS API for JavaScript​: "ArcGIS Server 10.1 supports CORS out of the box." OK, I have some problems now!! In same documentation: "For earlier versions, an administrator can add CORS support. Visit enable-cors.org for detailed instructions" Let's try anyway! Modified the web.config file on proxy application on IIS (from lines 07 to 15). <?xml version="1.0"?> <configuration>   <system.web>     <compilation debug="false" targetFramework="4.0"/>   </system.web>   <system.webServer>     <httpProtocol>       <customHeaders>         <add name="Access-Control-Allow-Origin" value="*" />         <add name="Access-Control-Allow-Headers" value="*" />         <add name="Access-Control-Allow-Methods" value="*" />       </customHeaders>     </httpProtocol>   </system.webServer>   <system.diagnostics>     <switches>       <add name="TraceLevelSwitch" value="Info" />     </switches>     <trace autoflush="true" indentsize="4">       <listeners>         <add name="agsProxyLogListener" type="System.Diagnostics.TextWriterTraceListener"              initializeData="C:\Temp\Shared\proxy_logs\auth_proxy.log" />         <remove name="Default" />       </listeners>     </trace>   </system.diagnostics> </configuration> Now, I get a new error! "XMLHttpRequest  cannot load http://server.virtual.private/DotNetProxy/proxy.ashx?http://server.virtual.private/arcgis/rest/services/teste/TEST_SERVICE/FeatureServer?f=json. Request header field X-Requested-With is not allowed by Access-Control-Allow-Headers in preflight response.". So, what's the correct way to configure the proxy? Because I do everything that was on documents, and got errors. ... View more

Trying to set the initial extent of map with same extent of a existing Feature Layer. Code: var featureLayer = new FeatureLayer("http://server/arcgis/rest/services/MyService/0", {   mode: FeatureLayer.MODE_ONDEMAND,   outFields: ["*"] }); featureLayer.on("load", function(e) {   var initialExtent = featureLayer.fullExtent;   map = new Map('map-view', {     basemap: "streets",     extent: initialExtent   }); } This don't work, and I have the following error on console: Map: Geometry (wkid: 31982) cannot be converted to spatial reference of the map (wkid: 102100) The Feature Layer was using the Spatial Reference wkid 31982. Why the map have the Spatial Reference wkid 102100? This is the only feature layer existing on code, and I "loaded" the Feature Layer before initialize the map, so, until I initialize the map, map = null What I need to do for the map start up with the same extent of the feature layer? ...

I have a feature layer with many features, and when I load on map viewer (Portal for Arcgis), I receive a message that 'Layer did not draw completely'. This is ok, because this layer don't have any visible range configured and have many features. But, when I try to use this feature layer on ArcGIS API for Javascript, the layer don't draw completely too, but I don't know how detect if this layer was draw completely or not (to show a message for the user). I already tried the 'update-end' event of feature layer, but this event don't show any error, even when the layer was not draw completely. Code: var featureLayer = new FeatureLayer("http://server/acgis/rest/services/ServiceTest/FeatureServer/0", {   mode: FeatureLayer.MODE_ONDEMAND,   outFields: ["*"] }); featureLayer.on("update-end", function(e) {   console.log(e); }); map.addLayer(featureLayer); ...
