title: Scrapy crawl and follow links within href
body: <p>I am very much new to scrapy. I need to follow href from the homepage of a url to multiple depths. Again inside the href links i've multiple href's. I need to follow these href until i reach my desired page to scrape.
  The sample html of my page is:</p>
  
  <p>Initial Page </p>
  
  <pre><code>&lt;div class="page-categories"&gt;
   &lt;a class="menu"  href="/abc.html"&gt;
   &lt;a class="menu"  href="/def.html"&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Inside abc.html</p>
  
  <pre><code>&lt;div class="cell category" &gt;
   &lt;div class="cell-text category"&gt;
   &lt;p class="t"&gt;
    &lt;a id="cat-24887" href="fgh.html"/&gt;
  &lt;/p&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I need to scrape the contents from this <strong>fgh.html</strong> page.
  Could anyone please suggest me where to start from. I read about Linkextractors but could not find a suitable reference to begin with. Thankyou</p>
