title: .condarc file updated for proxies but still cannot download packages
body: <p>I am working behind a Company Proxy and I wanted to install packages in anaconda. I tried it by generating the .condarc file and updating it for Proxy. Even after i included the Proxy it does not work and throws the error as below in Conda prompt. I have also included my .condarc file .I have included the correct proxies. But it does not work. Any suggestions?</p>
