[Zope] ImportExportFavorites

Hi guys i've got a small prob. I have the ImportExportFavorites util from microsoft. If that util post the bookmarks of an user then it sends with http_user_agent "FAVORITES" and file name "img.fav" Is there a way that zope get this file so I can save it in the ZODB. The source for sending the file is: <A HREF="javascript:window.external.ImportExportFavorites(false,'your server adress')" TITLE="Import Now" ALT="Import Now" ONMOUSEOVER="window.status='Import Now';return true;" ONMOUSEOUT="window.status='';return true;">Import Now</A>
