SSL protection on different directory

[Bryan]

Hi,       How to configure the mod_ssl so that it can allow some of the directories to be SSL protected? I have tried configuring SSLRequireSSL and SSLRequire but failed. I ran the HTTP as well as HTTPS on one apache server.       The situation is that there is a admin module in our system and everything under the /admin directory would be SSL protected. Would you suggest a method for configuration?      Thank you very much.
