HTTP_Request repeat querystring values

Hello, I have been using http_request for a while and it has been working great so far. I ran into my first issue today with it. I need to send out a url that has many values with the same name, for example: http://example.com?foo=bar&foo=blah&foo=test How can I do this? It seems that no matter what, it gets parsed by Net_URL which puts all the values into an array. Any ideas? Thanks Andrew
