NuGet behind a proxy

by

Here’s what I did to get this working with my corporate proxy that uses NTLM authentication. I downloaded NuGet.exe and then ran the following commands (which I found in the comments to this discussion on CodePlex):

nuget.exe config -set http_proxy=http://my.proxy.address:port
nuget.exe config -set http_proxy.user=mydomain\myUserName
nuget.exe config -set http_proxy.password=mySuperSecretPassword

This put the following in my NuGet.config located at %appdata%\NuGet (which maps to C:\Users\myUserName\AppData\Roaming on my Windows 7 machine):

<configuration>
    <!-- stuff -->
    <config>
        <add key="http_proxy" value="http://my.proxy.address:port" />
        <add key="http_proxy.user" value="mydomain\myUserName" />
        <add key="http_proxy.password" value="base64encodedHopefullyEncryptedPassword" />
    </config>
    <!-- stuff -->
</configuration>

Incidentally, this also fixed my issue with NuGet only working the first time I hit the package source in Visual Studio.

Note that some people who have tried this approach have reported through the comments that they have been able to omit setting the http_proxy.password key from the command line, or delete it after-the-fact from the config file, and were still able to have NuGet function across the proxy.

If you find, however, that you must specify your password in the NuGet config file, remember that you have to update the stored password in the NuGet config from the command line when you change your network login, if your proxy credentials are also your network credentials.
