Testing HTTPS without certificate

Hi - - - ---- - -- I have a typical setup -- my development machine, a testing server and, of course, the production server. My development machine, of course, doesn't have a Secure certificate, yet I need to be able to test https pages here, before getting to the testing server. (Currently, the testing server doesn't have one either, but that will be remedied shortly.) I know how to test for the existance of HTTPS, and stuff like that. So: Can one test https on a local machine? Resources, anyone? I have Googled my fingers off. Environment: PHP 5.2.5 Win 2K IIS 5 - or, if I need to - Mac OS-X 10.4 Apache? (I haven't set up the Mac as a server) - or - Linux (Ubuntu) with Apache (I am moving this direction and haven't yet learned how to run Apache) Ken
