Can the hyperlinks in a pdf be tracked for statistical purposes.

I have an online magazine which is published as a pdf file.  I want to be able to track the advertisers hyperlinks.  Checking with both Adobe.com and my hosting company I am lead to believe there is no way to track the click throughs of a pdf document.  Is there a way to track these?  If not, is there another adobe product which we could publish the magazine in to allow us to be able track the click throughs and forwards?

Any suggestions are greatly appreciated.
