paste the code first

import time

from tornado.gen import coroutine
from tornado.httpclient import AsyncHTTPClient
from tornado.ioloop import IOLoop
from tornado.web import Application, RequestHandler


class MainHandler(RequestHandler):

    @coroutine
    def get(self):
        client = AsyncHTTPClient()
        urls = ["http://www.baidu.com"] * 20
        start = time.time()
        yield [client.fetch(url) for url in urls]
        print(time.time() - start)


def make_app():
    return Application([(r"/", MainHandler), ])


if __name__ == "__main__":
    app = make_app()
    app.listen(8888)
    IOLoop.current().start()

I requested the same link 50 times in the http://localhost:8888/ get method through a browser, but found that the time it took was the sum of all the requests. Baidu found that requesting the same link would block, but did not find a solution.

tried to add different parameters to the link, but it was still blocked.

do you have a solution?
