For a static page, you could try modifying the markup to include a unique value in the query string even though that value is not used on the server. For example:

<iframe src="http://example.com/work.php?n=2&size=3&j=1&c=&code=1338387311039&ck=1">

<iframe src="http://example.com/work.php?n=2&size=3&j=1&c=&code=1338387311039&ck=2">

<iframe src="http://example.com/work.php?n=2&size=3&j=1&c=&code=1338387311039&ck=3">

This *should* force the browser to send separate requests for each.
