Displaying an external page using your own stylesheet

[Spyhop]

Hi - Does anyone know if it is possible (and how) to display a page from an external server using a stylesheet of your choosing rather than the one actually used?

e.g.

• User clicks http://banana.com/consumers/
  
• User is presented with the page from http://monkey.com/types/ using a stylesheet chosen by banana.com's admin, instead of the stylesheet actually used on http://monkey.com/types/.

I've not had much luck searching because there are many ways to word the question. Can this be done using javascript?

Isn't that a personal plugin? I mean making every visitor of banana.com see it that way.

Looking in to this still - would the best way be to put the external page in an iframe - then use javascript to do a search and replace of href="http://monkey.com/style.css" with href="http://banana.com/style.css" within the iframe's content at runtime?

Do browsers automatically 'refresh' in-memory 'pages' when you modify their source code at runtime? Bare in mind I know very little about web development

Thanks guys. I used the domains as an example - it's not for use the the public internet, so I'm not looking to nab someone's bandwidth / content!
