407 Proxy Authentication Required
asp.net, proxy
Solution
@Mohit Agarwal
Many thanks for suggesting adding ' useDefaultCredentials="true" ', you're a star!
I have been trying to get the .NET library for the Google Data API sample exe's working for weeks without success. Adding your suggestion fixed my problem and I now get a connection instead of 407 Proxy Authentication Required.
speadsheet.exe.config contents need to be:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy useDefaultCredentials="true">
<proxy usesystemdefault="true"/>
</defaultProxy>
</system.net>
</configuration>
In my case NOT as Google suggest:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<defaultProxy>
<proxy usesystemdefault="true"/>
</defaultProxy>
</system.net>
</configuration>

Problem
I am working on a website, in which I am retrieving XML data from an external URL, using the following code ``` WebRequest req = WebRequest.Create("External server url"); req.Proxy = new System.Net.WebProxy("proxyUrl:8080", true); req.Proxy.Credentials = CredentialCache.DefaultCredentials; WebResponse resp = req.GetResponse(); StreamReader textReader = new StreamReader(resp.GetResponseStream()); XmlTextReader xmlReader = new XmlTextReader(textReader); XmlDocument xmlDoc = new XmlDocument(); xmlDoc.Load(xmlReader); ``` This code is working fine on my development PC (Windows XP with .Net 3.5) But when I deploy this code to IIS (Both at Windows XP and at Windows Server 2003) it's giving me following error "The remote server returned an error: (407) Proxy Authentication Required." Sometimes it gives me "The remote server returned an error: (502) Bad Gateway." Following code is from my web.config ``` <system.net> <defaultProxy> <proxy usesystemdefault="False" proxyaddress ="http://172.16.12.12:8080" bypassonlocal ="True" /> </defaultProxy> </system.net> ``` Please help me ? [Edit] Even when i run the website for devlopment PC but through IIS it gives me error "The remote server returned an error: (407) Proxy Authentication Required." But when i run website from Microsoft Devlopment server, it is running fine
