redirect in cakephp ssl site routes to http not https

Question

I have developed a cakephp site that should use ssl for all pages. It works as expected except when I use redirect in a controller it redirects to http: //subdomain.domain.c

Answer 1

I found the error it was a misconfiguration of Apache.

Trying out Jamies solution, the site ended up in a redirect loop, because RequestHandler->isSSL() returned false even if the request was https. I then discovered that the $_SERVER['https'] was not set and the $_SERVER['port'] was 80, not 443 as expected.

At that point I have placed my ssl directives in sites-available/default,

SSLEngine on
SSLCertificateFile [path to cert file]
SSLCertificateKeyFile [path to keyfile]

Moving the ssl directives to the virtual host for the subdomain resolved the issue, with redirect loops.

Actually is also solved my initial problem because the method Router::url checks for $_SERVER['https'] if set it generates a url that starts with https: otherwise just http:

I have tested both Jameies solution and my own with rewrite rules in .htaccess and they both work as expected after the fix.
