[squid-users] Question regarding squid and url's

Hello,
I am attempting to do the following:
Type in http://10.0.0.1:3128/www.yahoo.com in my browser. I need to be able
to access a site like that because of some software we will be using that
does not have a proxy setting.
That gives me an error about not being able to bring up /www.yahoo.com.
Is there a different way of using the cache in the same manner? Or is there
a way to filter out the initial / ? Thanks for your help.
