It's pretty common in PHP where a header() function is used to redirect the user to a specify page.
[ Hide ] <?
header("Location: http://www.domain.com");
header("Refresh: 5; http://www.domain.com"); // Redirect after 5 secs
?>
The above code will work perfectly. However, given a URI
http://www.domain.com/file01.php?do=something#anchorhere
[ Hide ] <?
// This won't work with Opera 7.54 or even earlier,
// or this never worked before in Opera up to 8.5
header("Location: http://www.domain.com/file01.php?do=something#anchorhere");
// No problem for this though
header("Refresh: 5; http://www.domain.com/file01.php?do=something#anchorhere");
// A method to overcome the problem in Opera
header("Refresh: 0; http://www.domain.com/file01.php?do=something#anchorhere");
?>
Apparently, it's the '#anchorhere' in the URI that causes Opera failed to redirect to that page. According to the HTTP/1.1 protocol, there is no restriction for using #anchor for the URI inside the header's Location field. I haven't test this with IE and FireFox myself but there are reports saying both IE and FF are working fine.
