HTTPS installation/use

I've PHP 4.2.x running as ISAPI in a W2K Server/IIS 5 box... How to i setup SSL so i can receive HTTPS connections and install a certificate in the site to supply the SSL the required certificate? What i need to do is receive a HTTPS POST to a script that i supply the name and make HTTPS POST to a external web server... This is required to implement a transaction system with SSL security... On the other hand, the php_curl.dll gives me an missing library error when trying to start the web server with it loaded... Am I missing something? Thank you in advance for all the help, Luis Ferro TelaDigital.Net --- [This E-mail scanned for viruses by Declude Virus]
