title: Error when use "http" on query string PHP
body: <p>when i use an *<em>http://</em>*foo string on my page, i get error. </p>
  
  <p>For example: </p>
  
  <pre><code>http://www.myadress.com/process.php?url=http://foo
  </code></pre>
  
  <p>When i cut http:// , it works. What must i do to use http:// on query strings?</p>
  
  <p>i use url like this:</p>
  
  <pre><code>$address = @$_GET['url'];
  $source = file_get_contents($url);
  //bla bla
  </code></pre>
  
  <p>it displays <strong>404</strong> error.</p>
  
  <p>No change with encode.</p>
  
  <p>Always redirect to 404 error page. But when i erase http:// , it works. I wonder if it is because of .htaccess file?</p>
  
  <p><strong>here are .htaccess codes (wordpress classic):</strong></p>
  
  <pre><code>RewriteEngine Off
  #test
  # BEGIN WordPress
  &lt;IfModule mod_rewrite.c&gt;
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.php$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.php [L]
  &lt;/IfModule&gt;
  
  # END WordPress
  
  # Use PHP 5.3
  Action application/x-hg-php53 /cgi-sys/php53
  AddHandler application/x-hg-php53 .php 
  </code></pre>
