nit: If all arguments in function definition don't fit on one line with the
function name then you should put one argument per line.

It should be formatted as follows:
  void ChromiumPortAllocatorSession::SendSessionRequest(
      const std::string& host,
      int port)

   GURL url("https://" + host + ":" + base::IntToString(port) +
            GetSessionRequestUrl() + "&sn=1");
   scoped_ptr<net::URLFetcher> url_fetcher(
       net::URLFetcher::Create(url, net::URLFetcher::GET, this));
   url_fetcher->SetRequestContext(url_context_.get());
   url_fetcher->AddExtraRequestHeader("X-Talk-Google-Relay-Auth: " +
                                      relay_token());
   url_fetcher->AddExtraRequestHeader("X-Google-Relay-Auth: " + relay_token());
   url_fetcher->AddExtraRequestHeader("X-Stream-Type: chromoting");
   url_fetcher->Start();
   url_fetchers_.insert(url_fetcher.release());
