how to set reload button on html or php page?

Hello. I have a set of pages .html and .php which are connected by buttons. Each page contains a return button to go to the previous or x page. I would like that every time I click on return button, the page on which I fall is reload. i am on jQuerry mobile 1.4.5 and I use this code line for my back button:

  1. <a href=''../index.html" class="ui-btn ui-icon-back ui-btn-icon-left"> Back </ a >

Any help will save me. thanx in advance
