Force CPAN to download via HTTP

I'm about to lose my mind. How in the world do you tell CPAN to download via HTTP only? ...and NOT via a proxy.

From serverfault syn-

• Try these:

  Before running cpan: export -n http_proxy
  In the cpan shell: o conf http_proxy ''
  TO save your modified cpan config: o conf commit
  

  That will disable any http proxy CPAN is configured to use.

  From Jason

• If you don't want to use a cpan shell, you can also edit your cpan config file with a text editor, in unix systems it's here:

  ~/.cpan/CPAN/MyConfig.pm

  Of course, the field to change in your particular question is 'http_proxy'.

  From toshiro

• Try putting only HTTP URLs in your CPAN's Config.pm file, like:

  'urllist' => [q[http://cpan.cict.fr/], q[http://cpan.enstimac.fr/], q[http://mirrors4.kernel.org/cpan/]],
  

  I routinely do this and as far as I can see there's no FTP traffic to any CPAN mirror.
