Subject: Use location.replace for 404 redirect
X-Git-Url: https://git.ardis.lu/?a=commitdiff_plain;h=c45fe27bacf3463440b80a84f07498d05bc17c3b;p=ardislu.dev

Use location.replace for 404 redirect

This prevents adding an extra page in history, so users can press back once to go to the original page as expected.
