HTTP_Request Not likin' HTTPS:// urls

Hi, Seem to have some odd behaviour when asking HTTP_Request to post data to a https:// url. The url in question is https://select.worldpay.com/wcc/purchase and the return I get is:- ------------------------------------------------------------------------- Your browser sent a request that this server could not understand. Reason: You're speaking plain HTTP to an SSL-enabled server port. Instead use the HTTPS scheme to access this URL, please. Hint: https://mggwcc3a.select.worldpay.com/ ------------------------------------------------------------------------- I can make it work using ssl:// as the protocol instead - buy why? Do I need to ensure I have some version of a module hooked into PHP to use HTTPS:// with the PEAR HTTP_Request package? Somebody else asked the same question a while back on here and got no reply. I contacted him directly last week but still haven't had a reply so thought I would bring it up again.
