Okay, I'll explain the system I have working.

loginrequest is a simple function that takes two POST arguments from the two html forms. If the username is found in the users folder then it encrypts the password in md5 and matches it to that of the encrypted password in their data file from the users bin.

If they match, it creates a data file named their IP address, containing their userID (for me, 1) and a unique sessionID up to 25 random letters.

A cookie is then stored on the user's computer containing the exact same sessionID.

Then when you try to access modifyscores it opens up the data file named your IP address. If there is no data file named your IP it knows you haven't logged in. If there is, it sorts through all your cookies until it finds one with a matching session ID. Once that is found, it displays the data corresponding to the userID in the data file.

=D

And I think I'm going to stick with how I have it working right now. I like it how Python generates the html, because then I can combine elements from pages easily. What do <head> <body> and <html> tags do?

There are html and xhtml tutorials all over the place.

You MUST find at least a cursory explanation of HTML. Hell, even 2.0 will do.

That's probably the best method to do it; sites such as livejournal give the user the option of binding sessions to IP addresses.

But I think you might have made it a little complicated for yourself. I think you could you take advantage of CherryPy's sessions, like so:

(Toggle Plain Text)

if cherrypy.session.has_key("ipaddress"):
   if cherrypy.request.remoteAddr != cherrypy.session["ipaddress"]:
      return "Warning! IP Address doesn't match!"
else:
   cherrypy.session["ipaddress"] = cherrypy.request.remoteAddr

# output page normally

The makeup of a HTML file is:

(Toggle Plain Text)

<html>
 <head>
  ...
 </head>
 <body>
  ...
 </body>
</html>

The head contains all the parts of a HTML document that aren't directly displayed, such as the title, metatags, stylesheets and other such information. The body contains all the parts that are displayed.

So if we take your index page, it should look more like so:

(Toggle Plain Text)

<html>
<head>
 <TITLE>Jammers Base  v0.6  (O2Jam Scoring Site)</TITLE>
 <style type="text/css">
   h1 {
      border-width: 1;
      border: solid;
      text-align: center;
      border-right:2px solid #000;
      border-bottom:2px solid #000;
      margin-right:15px;
      padding-bottom:20px;
      }
   body {
      background-image: url(http://cold.byethost2.com/~Sane/bgimage.png);
   }
 </style>
</head>
<body>

The HTML you have on your site at the moment is a bit random, to say the least :o

That's because the html is all dynamically generated and drawn step by step through different functions. And it's not as if I know HTML very well ^^.
