* An demo illustrating how to retrieve a URI from a secure HTTP server.
*
* Author: Roy Wood
* Date: September 7, 1999
* Comments: This relies heavily on my MacSockets library.
* This project is also set up so that it expects the OpenSSL source folder (0.9.4 as I write this)
* to live in a folder called "OpenSSL-0.9.4" in this project's parent folder. For example:
*
* Macintosh HD:
* Development:
* OpenSSL-0.9.4:
* (OpenSSL sources here)
* OpenSSL Example:
* (OpenSSL example junk here)
*
*
* Also-- before attempting to compile this, make sure the aliases in "OpenSSL-0.9.4:include:openssl"
* are installed! Use the AppleScript applet in the "openssl-0.9.4" folder to do this!
