Caching files residing on a network share

Hi, I have a bunch of large static files on a website internal to my company and served by IIS. I rely on IIS' ETag and Last-Modified header handling to prevent the files being downloaded constantly by other systems, and thereby keeping those systems fast. I would like to remove the files from the local machine (which is running out of space) and place them on a network share. Would this arrangement create any problems for IIS to return consistent etags and also to speedily deal with if-modified-since / if-none-match requests? Does IIS do anything differently when serving files that are located on a share rather than locally? Thanks for your help,
