4.7 - I need to add "http://localhost:44300" into CORS policy for debug my project.

[TubaKumbara]

Hello.

I'm developing sceneView application and i can't see basemaps when i debugging my project on localhost (pressing F5). Because CORS policy blocking my localhost. But i see no error when i published my project.

I tried to add

esriConfig.request.corsDetection = false;

But doesn't worked.

AccessTo image at "https://myproxyserver/resource-proxy/proxy.ashx?http://myserver.com/myservice/3/5/1.jpg" from origin "https://localhost:44300" has been blocked by CORS policy: No "Access-Contol-Allow-Origin" header is present on the requested ressource. Origin "https://localhost:44300" is therefore not allowed access

Thanks inadvance.

Yes Exactly

My machine name is "goldone". 

proxy.config

<serverUrl URL="http://goldone" matchAll="true" />

<serverUrl URL="http://goldone:44300" matchAll="true" />

<serverUrl URL="https://goldone" matchAll="true" />

<serverUrl URL="https://goldone:44300" matchAll="true" />

JS file

urlUtils.addProxyRule ({ urlPrefix: "http://goldone", proxyUrl: "https://proxrserver/proxy.ashx"});

urlUtils.addProxyRule ({ urlPrefix: "http://goldone:44300", proxyUrl: "https://proxrserver/proxy.ashx"});

urlUtils.addProxyRule ({ urlPrefix: "https://goldone", proxyUrl: "https://proxrserver/proxy.ashx"});

urlUtils.addProxyRule ({ urlPrefix: "https://goldone:44300", proxyUrl: "https://proxrserver/proxy.ashx"});

My application running from VB.NET (with F5) starting as "https://goldone:44300"

Tuba, that looks good for the proxy rules now in the proxy.config you need to do the same for the serverURLs

[TubaKumbara]

Robert,

This is my proxy.config file which in same directory with proxy.ashx

<serverUrl url="http://goldone" matchAll="true" />
<serverUrl url="http://goldone:44300" matchAll="true" />
<serverUrl url="https://goldone" matchAll="true" />
<serverUrl url="https://goldone:44300" matchAll="true" />

Then there should be no reason for you getting that error then. I am not sure what to tell you.

[TubaKumbara]

Robert, Thanks for your interests. I know you want to help but i can't to say anything else. I can't debug my codes,

Same sceneview running good when i publish my application to another server. But this is hard to debug from developer console.

[RobertScheitlin__GISP]

I personally do not use Visual Studio for development. I use Atom.io for my js development IDE and just do my debugging in Google Chrome.

[TubaKumbara]

Thanks for suggest.

Robert,

I found the problem. My proxy file is not on my machine. I 've added Some variables to my proxy machine's http response headers.

My fault is that i searching error on my machine since 2 days. Actually error was in proxy machine's proxy web application configuration.

My problem solved and working now. I'm happy.

Thank you again for all help. 

Here is the picture where i added variables
