I am not saying use directory level permissions. My post does not assume a simple level of yes or no auth. I am saying use a session. If the user connects without a valid session pass him the the session creator. If the has access to the base app (via IP or whatever your base auth level is), then grant him a session and redirect back to the page he tried to hit. If the user then needs expanded access have a login page that verifies whatever auth you want and grants auth level tokens and stores them in his current session. This resolves the base users from getting user/pass auths while still allowing you to have fine grained auth privs for advanced users. Then your cgi can take a look at the session and form the pages and options to something that is acceptable for the auth privs that the session grants. Make sense?

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
