title: creating back page links in Codeigniter
body: <p>I have a page with URL <a href="http://arslan/admin/category/index/0/name/asc/10%29" rel="nofollow">http://arslan/admin/category/index/0/name/asc/10</a> in Codeigniter.
  In this URL, the <code>uri_segment</code> start from <code>0</code>. This (<code>0</code>) is the default search value, <code>name</code> and <code>asc</code> are the default sort field and order, and 10 is the pagination index.</p>
  
  <p>Now if I move to an add page with URL (http://arslan/admin/category/add/)
  similarly like above "add" is the current function.</p>
  
  <p>Now if i want to go back through a link to back page... How can I divert the user back? I can't make the URL go back.</p>
  
  <p>Can somebody help me please?</p>
