http_proxy: disable yum for a particular repo

[Ezequiel Alfie]

Hello,

I have to use an http proxy to access http outside my lan. So I use the 
http_proxy variable.

I'm setting up a local repository for which I don't want the proxy usage. 
According to yum documentation I should set proxy=_none_ on the particular 
repository. I've done that and it doesn't work: yum still uses the http 
proxy. I also tried using the no_proxy environmental variable.

Has anyone work around this? Is this a known bug/issue? Is there a way to 
solve it?

Thanks in advance,
Ezequiel
