You have selected the integer %d.<p>
You can compute its <a href="factorial">factorial</a> (%d!)<p>
Or, you can visit the web page for the
<a href="../%d/">previous</a> or
<a href="../%d/">next</a> integer.<p>
Or, you can use redirects to visit the
<a href="prev">previous</a> or
<a href="next">next</a> integer. This makes
it a bit easier to generate this HTML code, but
it's less efficient -- your browser has to go through
two request/response cycles. And someone still
has to generate the URLs for the previous/next
pages -- only now it's done in the <code>prev()</code>
and <code>next()</code> methods for this integer.<p>
