I'm not sure how OSX Server works, but I believe that what you want to do can be completed using VNC.
Here is a quick guide I found on youtube on how to create VNC on your Mac computer so that you can manage it from another computer by logging into the VNC server.
You will not be able to use your browser to log in, so you will need to download a third-party application (tightVNC is indicated in the video) in order to access your mac remotely.
