A page on my site has links that used to open in a new window, but now they open in an iframe. I redesigned the pages that are linked to so they will look better in the iframe. The problem is, anyone who has already visited my site will have the old pages cached in their browser. Does anyone know of a way to force pages linked to and opened in the iframe to be reloaded (apart from giving each linked page a new name?)
You can also trick browsers into thinking that you are always loading a new page in the iframe by passing a dummy parameter to the page. For example: <iframe src="somepage.html?dummy=x> x is some random number, generate that with php or javascript.
