Caching

After updating an html file (taken from a previous/template file) I saved my changes, copied to my server’s pub folder, and posted the URL onto Facebook. Then I noticed that I forgot to change the title. How-come the title from old won’t go away? I tried numerous things (like copying to diskette to remove security permissions) and re-posted. Is Facebook caching, or my computer?
