Can the MediaWiki API retrieve the HTML of a wiki page, if that page changes its rendering based on the URL query string?

For example, if I have an article “Foo” with the URL:

http://wiki.example.com/wiki/Foo

and it renders *different* HTML if I pass the query parameter “bar”:

http://wiki.example.com/wiki/Foo?bar=1

can the MediaWiki API pass along "bar=1" and retrieve the HTML produced by the second URL?

I know I can retrieve “Foo” using action=’parse’, prop=’text’, page=’Foo’. But I can’t find any way to pass a URL query parameter along with the call and have it take effect.

Thanks for any assistance, DanB
