title: Wordpress rewritten URL structure
body: <p>My Wordpress site can be broken in two parts:<br></p>
  
  <ol>
  <li>Content type as pages, having URLs like: <code>site.com/page/subpage/</code></li>
  <li>Content type as posts, having URLs like: <code>site.com/category/postname/</code>.<br></li>
  </ol>
  
  <p>The URL <code>site.com/blog/</code> is a page having a "Blog posts" template. If I open one of the listed posts, I get redirected to <code>site.com/category/postname</code>, <strong>but I'm interested to have <code>/blog/</code> in front of it</strong>, like the following: <code>site.com/blog/category/postname</code>. Also, if I try to access a blog post without <code>/blog/</code> in front, I want to be redirected to the correct URL.<br></p>
  
  <p>Another thing, the archive is of the form <code>site.com/01/2013/</code>, <strong>but I would like to be like: <code>site.com/blog/archive/01/2013</code></strong>. <br></p>
  
  <p>My question is: how can I rewrite the URLs so that I can those bolded above; to have <code>/blog/</code> in front of the <code>/category/</code> and <code>/blog/archive/</code> in front of <code>/01/2013/</code></p>
