Can't get rid of domain name in links even though it has been changed on the settings page

Hi,
I'm using this fantastic module to run a site on two domains. The main one is in English, let's call it domain1.com , the second is in Hebrew: domain2.co.il. Everything is working great.
I cloned the site to a development machine so I could do all sorts of testing and I where I use domain1.info and domain2.info instead of the real domains.
I changed the domains in /admin/build/domain to domain1.info and domain2.info but while for domain1.info everything is working well, all the links in domain2.info (such as the links in /admin) point to domain2.co.il.
I looked inside the db, (particularly in the domain conf table, after I unserialized it of course) but could not find any occurrence of domain2.co.il
I'm not sure whether this is a bug or a case of me missing something (although I spent countless hours going over the settings).
Any idea how I can fix this issue?
