[cgiapp] CGI::Application::FastCGI -> The page isn't redirecting properly???

[CGI User]

Hello,

I encounter very strange problem using CGI::Application::FastCGI module.
Firefox browser displays this warning:
"The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address 
in a way that will never complete."
when I try to redirect to another page using CGI::Application::Plugin::Redirect 
module.

I check session conditions in cgi_prerun method like this:
sub cgiapp_prerun {
     my $self = shift;
     my $rm = $self->get_current_runmode;

     # Get sess_id from URL
     my $url_sess_id = $self->get_sess_id('url');
     my $sess_id = $self->param(('sess_id');

     # 1. No sess_id in URL
     if (!$url_sess_id) {
         $self->delete_old_sess($sess_sess_id) if $sess_sess_id;
         $self->create_new_sess;
         return $self->redirect('warning.html');
     }

     return $self;
}

However, when I switch back to the plane CGI::Application module, everything 
works very well.

I'm using fcgid (replacement for fcgi) module with Apache.
I checked my fcgid and Apache configurations. Everything works properly.

If I use CGI::Application::FastCGI module and comment out 
'$self->redirect_url('warning.html');' line - the application works correctly.

Could somebody tell me please why CGI::Application::FastCGI module doesn't 
redirect to the proper HTML page when CGI::Application does it all the time?

Many thanks in advance,

Alex
