you must using httpclient 3.1, since testing indicates httpclient 3.0 fine url. httpclient 3.1, throws error when gets [ in query string. why case not sure. according rfc 3986 both [ , ] should allowed. looking @ uri source in httpclient 3.1 doesn't include characters reason. possibly bug in version say. being said, don't think there work going httpclient 3.x since 4.x focus.
