title: .htaccess error redirecting to another directory
body: <p>I'm having problem with .htaccess that rewrite my url. I created a simple dynamic website and I cant figure how to fix it. This is my login url localhost/foss/ then after successful login the user will be redirected to localhost/foss/main</p>
  
  <p>here is the code of my .htaccess</p>
  
  <pre><code>RewriteEngine on
  RewriteRule ^([a-zA-Z0-9_-]+)$ index.php?p=$1
  RewriteRule ^([a-zA-Z0-9_-]+)/$ index.php?p=$1
  </code></pre>
  
  <p>and here is my php that handle include files depending on the p value.</p>
  
  <pre><code>&lt;?php
      $page = $_GET['p'];
      $pages = array('home', 'inv_view', 'inv_add', 'inv_delete', 'inv_edit', 's_view', 's_add', 's_delete', 'change_pass', 'register', 'logout');
      if (!empty($page))
      {
          if(in_array($page, $pages))
              include $page . '.php';
          else
              echo 'Page not found!';
      }
      else
          include 'home.php';         
  ?&gt;
  </code></pre>
  
  <p>this is working fine, the only weird things that going on, is after the user is redirected to the localhost/foss/main, the .htaccess rewrite the url to localhost/foss/main/?p=main, but when i choose a link like localhost/foss/main/home it will work normally. how can i get rid of the ?p=main after the user login and redirected to localhost/foss/main</p>
