Page Monitor Bookmarklet That Clears Cookies or Cache After Each Reload

Question

Okay I changed the plan. How would I create a bookmarklet that refreshes a link and clears cache until a page change is detected?

Edit: this might help (from JavaScript Bookmarklet; click button, reload page, then open page): If a page reloads, any code currently running on that page, including code from a bookmarklet, is ended and removed. Traditionally bookmarklet code ceases to work after a page load and user clicks it again.

There are three workarounds that I know of.

A.) Change the process that loads the page to instead use AJAX.

B.) Change the process that loads the page to instead open a new window, and then use JavaScript to manipulate the new window.

C.) Before triggering the page load, open a new child window and insert code into it. The code in that child window can then monitor its parent and take actions on the parent even after the parent has reloaded.

Edit 2: this refreshes the page, so now I just need to clear cache on each refresh and stop when a page change is detected (overall function is like a page monitor but clears cache after each refresh).

---or----

javascript:
timeout=prompt("Set timeout [s]");
current=location.href;
if(timeout>0)
  setTimeout('reload()',1000*timeout);
else
  location.replace(current);
function reload(){
  setTimeout('reload()',1000*timeout);
  fr4me='<frameset cols=\'*\'>\n<frame src=\''+current+'\'/>';
  fr4me+='</frameset>';
  with(document){write(fr4me);void(close())};
}

Edit 3: found this for clearing cookies (which should be sufficient):

Edit 4: this checks for page changes:

Now how do I put this together?
