title: Modify crawled URL before indexing it
body: <p>I am using nutch 1.4. I want to manipulate the crawled url before indexing it.</p>
  
  <p>For example, if my URL is <a href="http://xyz.com/home/xyz.aspx" rel="nofollow">http://xyz.com/home/xyz.aspx</a> then I want to modify the URL to <a href="http://xyz.com/index.aspx?role=xyz" rel="nofollow">http://xyz.com/index.aspx?role=xyz</a> and only the latter field should be indexed in SOLR. The reason is I don't want to expose the first URL. The 2nd URL will ultimately redirect it to same page.</p>
  
  <p>Do we have a provision in Nutch to manipulate the crawled URL's before indexing it to SOLR??</p>
