geoip rewrite

[robv]

was wondering if someone could help me out with a rewrite rule.
i need to rewrite anyone who comes to the main site (ie. www.test.com) with no request_filename and is from canada to be redirected to a different page.

i got the geoip working just fine 

if  ($geoip_country_code = 'CA') {

}

but i can't figure out how to do the combination of the geo and the frontpage only.

any help would be appreciated
