Passing an internet proxy with credentials for Flexviewer

[Anonymous User]

Dear all,

Do any of you have experience on how to get the Flexviewer to pass map requests to the arcigsonline services through an internet proxy that requires login/pwd ?

Basically, I want to avoid the proxy credentials popup in my browser while accessing an internet webservice from the Flexviewer.
I know how to do this in BlazeDS for regular Flex webservice calls, this does not work with the FLEX API mapservice calls 😞

Thanks for any ideas that can point me in the right direction.

Best

Hi Michael,

Thanks for your input, and yes, I have seen and tried this. The way I understand it, this approach will allow me to connect to secured services on a external domain. What I want to do however, is connect to plain old non secured webservices, but  through a corporate internet proxy that requires authentication.

The setup mentioned on the link above does not allow for this as far as I can figure out.

After some further digging, I solved this issue using the proxypage .NET approach.

Basically, you need to modify the proxy.ashx handler in the following way (C#.NET) - modifications in bold

*******************************************************************************
public void ProcessRequest(HttpContext context)
        {

            //Added code for passing your local webproxy
            WebProxy proxyObject = new WebProxy("http://999.999.999.999:1234/", true);
            NetworkCredential myCreds = new NetworkCredential("username", "password","domain");
            proxyObject.Credentials = myCreds;
       

            HttpResponse response = context.Response;

            // Get the URL requested by the client (take the entire querystring at once
            //  to handle the case of the URL itself containing querystring parameters)
            string uri = context.Request.Url.Query.Substring(1);

            // Get token, if applicable, and append to the request
            string token = getTokenFromConfigFile(uri);
            if (!String.IsNullOrEmpty(token))
            {
                if (uri.Contains("?"))
                    uri += "&token=" + token;
                else
                    uri += "?token=" + token;
            }

            System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(uri);
//Add proxy to your HttpWebRequest
            req.Proxy = proxyObject;
            req.Method = context.Request.HttpMethod;
            req.ServicePoint.Expect100Continue = false;
            req.Referer = context.Request.Headers["referer"];


..... code continued

Hope this is useful to someone. It works out very well for me.
