[Yum] Yum conf question

[Bryan Seitz]

Yummers,

    Say I have the following:

[base]
name=RHEL $releasever - $basearch - Base
baseurl=http://server1.blah.com:8080/RHEL/$releasever/rhn
         http://server2.blah.com:8080/RHEL/$releasever/rhn

Is there a method to how it picks the mirror to use?  It seems like
currently it choose one at random.  I would like to be able to define
a primary that will always be tried first.  Any help would be
appreciated.
