in reply to Failure to redirect when my CGI::Application powered site is used under mod_perl2

In plain CGI-mode this works. In mod_perl it gives me the following output direct to my browser:

Try

lwp-request -m get -USsexd http://whatever/cgi/ lwp-request -m get -USsex http://whatever/cgi/

    I'm not familiar with those commands, but here is what they produce:

    (Please excuse the formatting.)

      To reply to myself it seems that I have two solutions:

      • Use CGI::Application::Plugin::Redirect
      • Update my code:
      sub redirectURL { my ( $self, $url ) = (@_); $self->header_type('redirect'); $self->header_add( -url => $url , -status => 301 ); return; }

      That redundent "return" seems to make things work properly in my demo and real application.

      I guess the return value of "header_add" is causing problems ..
