title: Special characters in document.location.href
body: <p>Is it bad practice to make a page that has a web address like these:</p>
  
  <pre><code>http://example.com/-products-and-services.php
  http://example.com/-contact-us.php
  http://example.com/--books.php
  http://example.com/--translation.php
  http://example.com/--illustration.php
  http://example.com/-$-special-feature.php
  http://example.com/-$-vip-area.php
  </code></pre>
  
  <p>Will google or apache have problems with these (- $) characters?</p>
  
  <p>I am doing this because I makes it easier for me to view and categorise pages while still letting me add keywords to the file names.</p>
  
  <p>Thanks</p>
