Favicon is one of the hardest. Ctrl-F5 doesn’t help. You can of course see the source, find the location of the favicon, click on it (if you use Firefox or Chrome), otherwise copy the url and paste it in the address bar. When you load it separately, the favicon cache is renewed. It works. But if you want to make it easier for your users, set a version to your favicon file in the masterpage:

It is easy to use a custom favicon, put a ico image into a mapped folder Images and then locate this line in your master page: <SharePoint:SPShortcutIcon runat="server" IconUrl="/\_layouts/images/favicon.ico" /> ```And replace it with your ico: <SharePoint:SPShortcutIcon runat=“server” IconUrl="/_layouts/images/CONTOSO/favicon.ico" />

För att använda egen favicon, lägg till följande rad i din masterpage (inom head): <link rel="shortcut icon" href="/\_layouts/images/YOUR.PROJECT/favicon.ico" /> ```Skapa en ikon och lägg den i mapped folder Images.
