How to whitelist an URL in Privoxy (with a little regexp)

Question

how can i whitelist these URLs in Privoxy?

http://foo.org/user/10000/track?page=1
http://foo.org/user/10000/track?page=2
http://foo.org/user/10000/track?page=3
http://foo.org/user/10000/track?page=4
...

I don't want to whitelist "foo.org" i just need to whitelist these specific url's.
the "page=NUMBER" where NUMBER=1..99999999 [so it's a big number, i don't know exactly how much]
What do i need to write in the "user.action" file? :\

Answer 1

http://foo.org/user/10000/track\?page=[0-9]+

Should work

Answer 2

this should work, unless you need it to be more specific

{-block -filter}
foo.org/user/10000/track\?page
