Maybe you're missing the return HTTP_REQ_ACCEPT from the end of your filterURL() method?

I've just checked it and setting self.request_url seems to be working just fine for me,

MatcherPolicy(name="DNS", matcher=DNSMatcher(hosts=("google.com")))

class TestHttpProxy(HttpProxyNonTransparent):
    def config(self):
        HttpProxyNonTransparent.config(self)
        self.request["GET"] = (HTTP_REQ_POLICY, self.checkurl)
        self.request_header["Host"] = (HTTP_HDR_POLICY, self.checkhosthdr)

    def __post_config__(self):
        # check client IP address with DNSMatcher
        matcher = getMatcher("DNS")
        if matcher.checkMatch(self.session.client_address.ip_s):
            proxyLog(self, HTTP_DEBUG, 3, "Matcher matched")

    def checkurl(self, method, url, version):
        proxyLog(self, HTTP_DEBUG, 5, "Checking URL; url='%s'", (url,))
        self.request_url = "http://google.com/"
        return HTTP_REQ_ACCEPT

    def checkhosthdr(self, name, value):
        if name == "Host":
                proxyLog(self, HTTP_DEBUG, 5, "Processing header; name='%s', value='%s'", (name, value))

        return HTTP_HDR_ACCEPT

    def connectServer(self):
        # check server IP address with DNSMatcher
        stream = HttpProxyNonTransparent.connectServer(self)
        matcher = getMatcher("DNS")
        if matcher.checkMatch(self.session.server_address.ip_s):
            proxyLog(self, HTTP_DEBUG, 3, "Server matched")
        return stream

def http_test():
        Service("http1", TestHttpProxy, router=InbandRouter())
        Dispatcher(transparent=FALSE, bindto=DBSockAddr(SockAddrInet("127.0.0.1", 8765), protocol=ZD_PROTO_TCP), service="http1")
