Hi Thomas, I still can't replicate this issue. I'm using v12.4.0, but the proxy code hasn't changed from v12.3.0. Here's how I am testing, that may give a hint about what's going wrong.
- Setup a proxy using squid: http://news.softpedia.com/news/Seting-Up-a-HTTP-Proxy-Server-with-Authentication-and-Filtering-52467.shtml - Downloaded http://google-api-adwords-dotnet.googlecode.com/files/awapi_dotnet_lib_src_12.4.0.zip. - Extracted the project and opened AdWords.v2008.sln in VS 2008. - Set the proxy url, username, password in examples\csharp\App.config. - Set Developer token, Email, password, ClientEmail in examples\csharp\App.config - Run AdWords.Examples.CSharp with command line argument as v201101.GetAllCampaigns. My call fails for wrong username/password (407 Proxy Authentication required) and succeeds for the right username/password in App.config. Cheers, Anash P.
