[Javascript] Onload and onunload spinner

Could you attach a random query string variable to the end of the links?
So even if it is the same page it will change the src like have 2 links to
the same page but with a random variable such as

mypage.php?rnd=3r09fj340f
mypage.php?rnd=sdfojh30sd

or are these links within the frame which you have no control over?

The only other way that comes to mind atm is to use a server side proxy. All
links actually point at the proxy and pass the correct link url in as a
param. The proxy does a get on the param page and displays it in the frame.
That way you could locate the proxy page on the same domain so javascript
could interact with it and you could include additional code in the page to
trigger functions in the page holding the frame? (long way round for a
shortcut I know - lol!!)
