The Adobe PDF plugin accepts arguments in a url, anything after a # is passed to the plugin. There was a vulnerability because of this.
To jump to a specific page, put #page= after your link. http://www.math.ias.edu/~avi/PUBLICATIONS/MYPAPERS/DSW06/dsw06.pdf#page=6
To zoom in to a specific zoom, you can also put #zoom= after your link. http://www.math.ias.edu/~avi/PUBLICATIONS/MYPAPERS/DSW06/dsw06.pdf#page=2&zoom=50
Google has been using the search feature, to do that, put #search="search terms" after your link. Example: http://www.math.ias.edu/~avi/PUBLICATIONS/MYPAPERS/DSW06/dsw06.pdf#page=2&zoom=50&search='Tensor'
