modify a url

[admin]

Is it possible to change a value in URL as it hits the browser.

If a page has a URL of:
<!-- w --><a class="postlink" href="http://www.somesite.com/ViewJob.htm?JobNumber=27">www.somesite.com/ViewJob.htm?JobNumber=27</a><!-- w -->

Is it possible to change it to:
<!-- w --><a class="postlink" href="http://www.somesite.com?ViewJob.htm?JobNumber=28">www.somesite.com?ViewJob.htm?JobNumber=28</a><!-- w -->

so that if someone refreshes the page it will go to a different page.
