.NET proxy url duplicate

[KhanhPham1]

Could someone point in the right direction as to why the proxy duplicate the url:

https://localhost/proxy/proxy.ashx?https://localhost/proxy/proxy.ashx?https://services.arcgisonline....

This is my proxy.ashx

<?xml version="1.0" encoding="utf-8" ?>

<ProxyConfig allowedReferers="*" logFile="proxylog.txt"

             mustMatch="false">

    <serverUrls>     

        <serverUrl url="https://services.arcgisonline.com"

                   matchAll="true"/>       

        <serverUrl url="https://server.arcgisonline.com"       

                   matchAll="true"/>      

    </serverUrls>

</ProxyConfig>

Khanh,

   Can we see where you define the esriConfig.defaults.io.proxyUrl portion in your code?

Of course...viewer.js

Khanh,

   You are not manually appending the proxy.ashx to any of your url strings in your code are you?

Some advice, I never use localhost. I always use my machine name (i.e. gislap183). There is probably no reason to use "alwaysUseProxy" as true. You only want to proxy urls that require proxy'ing.

Robert,

No, I'm not manually appending anything.  When I turn off "alwaysUseProxy", I get the login form even though I have "urlUtils.addProxyRule." I'll change localhost to machine name and see if that helps.

Thanks for your input.

For others that might have the same problem.  I solved it but not sure if it's best practice.

esriConfig.defaults.io.proxyUrl //removed

esriConfig.defaults.io.alwaysUseProxy = false;

urlUtils.addProxyRule({

        proxyUrl: "https://xxxx/proxy/proxy.ashx",

        urlPrefix: "https://xxx/arcgis/rest/services/xxxx/xxxx/MapServer",

        accessToken: "1xxxxxxxxxxxxxxasdfasdfasdfasdfasdfasdfasdfasdf"

    });
