I have found a workaround for this problem. I just hook into the wp_redirect filter and add a “Connection: close” HTTP header.
function close_connection_after_redirect($location,$status) {
header("Connection: close",true);
return $location;
}
add_filter('wp_redirect','close_connection_after_redirect');
I haven’t found out yet what has actually caused the redirect loop, but this workaround solves the problem for me.
