restricting access to some template pages

I have been asked to create a secure download page, using a page based on a PowerCMS template, as the site uses this extensively

Obviously, I only want a specific page to be restricted, without affecting other pages based on this template.

The approach I have taken is to check the page url for a certain string, and if present, load the conditional content.

The same logic applies when checking for page access.

eg to check which page is loaded

php:
<?php

  $url 
$_SERVER['REQUEST_URI'];
  
$downloadspage = (stristr($url'downloads') === FALSE)?'0':'1';
  
$loginpage = (stristr($url'login') === FALSE)?'0':'1';
?>



to check if admin is logged in

php:
<?php if ($loginpage === '1'  {

  if (!
WA_Auth_RulePasses("Administrator")){
    
WA_Auth_RestrictAccess("redirectpage.php");
  }
?>



I plan to store the files themselves outside of the site root and use WA file manipulation to download

As it is all server side, it seems a safe, sensible way to go about it, but as the client is very cautious re security, I wanted to check that it seemed a sensible approach to take, as I haven;t done this with PowerCMS pages before, and wondered if there were any additional measures or other course I should take

this won't be very secure using a URL variable. any body could add the URL variable to gain access.

The page access uses a security assist access rule that is based on a session variable set at login. you can create additional access rules and use the security assist show region to show the content if the access rule is met.

Sorry, maybe i wasn't clear enough im my meaning, i am not using the url itself as security.

Access to the url, i'm not bothered about, - using the url variable is only giving me a value so i can set some conditions to tell the page which sections to load.

eg load a login form on a login page

I am doing this as the page is based on a PowerCMS template

The access rule is initiated only if the page has a string in the url, as i only want to invoke the access rule on specific 'pages'

so for example, the secure page is part of the general page template.

only if this 'page' is loaded, the access rule is initiated.

The access rule uses the same login security as power cms, and limits access to members with an entry in the users table

(I have further secured PowerCMS so this is now only available to Super Admin, - as is in-line editing, by changing the rules in WA_CMS.php)

Does that make more sense, or is this scenario still insecure ?

Ok, yeah, that makes more sense. I don't see an obvious flaw in this.
