title: JQM page id and data-url
body: <p>What is the relation between page id and data-url attribute. Is there any relation. Is it fine to change the data-url attribute.</p>
  
  <p>My issue is that there is a page to which i pass the params using changePage. I also specify the data-url in changePage. After going to that page, if i manually refresh the page a new page is added since the data-url is different for that page. That is, the data-url becomes same as the page id. Hope that am clear on this. What should i do so that the page is replaced during manual refresh of page. </p>
  
  <p>And, can someone please explain how JQM uses page id and data-url. Thanks in advance.</p>
