I have recently started switching all my sites to SSL, locally using Mamp Pro virtual hosts and self-sign certificates.
All works fine with one exception: if I type local.domainname.co.uk in a browser I get a 403 error, unless I type the full https:// first, then it works fine. On the live site it all works as expected; type domainname.co.uk and the browser fills in the https:// for me. These are drupal sites using htaccess module to force the ssl - but since it works live but not local I'm assuming its a mamp issue?
