If you are loading different page after the operation (branch or
node delete whatever) ,you could say document.location.replace("anotherpage.jsp/html")
which will remove the previous URL from the browser history and hence
your browser 'back' button won't load the page again.
Otherwise,you could use response.setHeader("cache-control", "no-cache") to
remove the browser cache and hence the browser 'back' button will re-load
the page with current data.
Hope this Helps ...

rathna.
