In JavaScript I am adding a proxy rule as such....

		
urlUtils.addProxyRule({
	urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/Test/FeatureServer/0",
	proxyUrl:  "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx"
		
});	

 

But I have a .Net app that I need to call a GP Service from C#     BUT     I want to run it through the proxy so Credentials are not needed....

How would I modify this code to work in C# so I can use it to bypass credentials on a secured GP Service

urlUtils.addProxyRule({
	urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/Test/GP_TOOL/",
	proxyUrl:  "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx"
		
});

I got it with this....I went another route and got a Token for the service....I will simply apply that to the Service when I call it to satisfy the Credentials needed.

 

        // GET TOKEN
        public String GetToken()
        {
            string result = null;
            try
            {
                string gpUrl = "https://xxxx.xxxx.xxxx.gov/arcgis/tokens/generateToken?username=User&password=U$er&expiration=15&f=json";
                string reqString = gpUrl;

                HttpWebRequest req = WebRequest.Create(new Uri(reqString)) as HttpWebRequest;
                req.Method = "POST";
                req.ContentType = "application/json";
                // Encode the parameters as form data:
                byte[] formData = UTF8Encoding.UTF8.GetBytes(reqString);
                //req.contentLength = formData.Length;
                // Send the request:
                using (Stream post = req.GetRequestStream())
                {
                    post.Write(formData, 0, formData.Length);
                }
                // Pick up the response:
                //string result = null;
                using (HttpWebResponse resp = req.GetResponse() as HttpWebResponse)
                {
                    StreamReader reader =
                    new StreamReader(resp.GetResponseStream());
                    result = reader.ReadToEnd();
                    Console.WriteLine(result.ToString());
                }
                return result;
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                result = ex.Message;
                return result;
            }
        }

In my Web.config I have the URL referenced

      <setting name="deletePoints_Dev" serializeAs="String">
        <value>https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/GPToolEditor/FeatureServer/0</value>
      </setting>

When I go to use this GP Tool I do this

        public Boolean DeleteAllPointsFromTable()
        {
            try
            {
                string whereClause = "OBJECTID>-1";
                string gpUrl = deletePoints_Dev;
                if (production) gpUrl = deletePoints_Prod;

                string reqString = gpUrl + "/deleteFeatures?where=" + whereClause;

 

BUT I am going to lok down this GP Tool URL like a Feature Service.  Where in this workflow would I add the Proxy to bypass this authentication?

WHERE do I put this Proxy Rule?

HOW do I write this in C#

		urlUtils.addProxyRule({
			urlPrefix: "https://xxxx.xxxx.xxxx.gov/arcgis/rest/services/Testing/GPToolEditor/FeatureServer/0",
			proxyUrl:  "https://xxxx.xxxx.xxxx.gov/DotNet/proxy.ashx"
		});
