title: Why does my URL Rewrite rule cause too many redirects on apache?
body: <p>I try to change the URLs to my products, so the <strong>categories</strong> between <strong>host</strong> and <strong>product-identifier</strong> wont be displayed anymore:</p>
  <p>From:
  <code>www.myexampleshop.de/pants/shortpants/123456790-exampleshortpants</code></p>
  <p>To:
  <code>www.myexampleshop.de/123456790-exampleshortpants</code></p>
  <p>My rewrite Rule is builds the URL correctly:</p>
  <pre><code>RewriteEngine on
  RewriteRule ([\/a-z]+)(?=\d{10}-)(.+) $2$3 [R]
  </code></pre>
  <p>But my browser tells me I have too many redirects. How is that possible?</p>
