how to redirect from https to http

[Jonh Smith]

Hello

I have a servlet protected with <transport-guarantee>CONFIDENTIAL</transport-guarantee>, which correctly makes glassfish generate an automatic redirection response to the https port, when i use that servlet's mapped url in the browser. However, once there, any redirection to some unprotected resource keeps using the htpps protocol, not http and i don't want that. How can i do a response.sendRedirect(/*WHAT DO I PUT HERE?*/) that acomplishes this ? That is, if i use

response.sendRedirect(getServletContext().getContextPath() + "/myurl");

the server response redirect location is for
https://localhost:8082/mywebapp/myurl,

instead of
http://localhost:/8081/mywebapp/myurl

Thank you

    if(request.getScheme().equals("https"){

//Construct your own redirect url

String redirect = "http://"+getServletContext().getInitParameter("domain")+request.getContextPath()+"/myurl";

response.sendRedirect(redirect);
}
// put a context init parameter named domain which has your domain name as value.

I wasn't very happy with hard-wiring the domain name so googled around and made a small change to your suggestion:

String redirect = "http://"+ request.getServerName()+":"+ getServletContext().getInitParameter("http_port")+"/"+request.getContextPath()+"/myurl";

Thank you very much for your help!
