[aur-dev] [PATCH] Return 404 error page if invalid package ID is used

[Lukas Fleischer]

We already display the 404 error page if someone tries to access an
invalid package via virtual URLs ("/packages/nonexistent"). Add the same
check to "web/html/packages.php" to make sure the same error is shown if
a user requests package details of a nonexistent package ID via legacy
URLs ("/packages.php?ID=-1").
