hi，about the http sequence #417

Open suppersam1 opened 1 year ago

suppersam1 commented 1 year ago

Hi, may I ask if the HTTP requests from the same route in the crow are strictly executed in sequence, and if the requests from the same route are stored in a queue and then executed in FIFO order

suppersam1 commented 1 year ago

I'm not very familiar with boost:: asio:: io_ service, I have looked at the code for crow and found that without opening multiple threads, only one thread calls boost:: asio:: io_service. run() method. Does this mean that HTTP requests will be executed sequentially?

not exactly, io processes have also wait states where the next request can be started. so they can be executed at least partially overlapping. maybe that is a good start to read: https://think-async.com/Asio/asio-1.26.0/doc/asio/overview/model/async_ops.html

Is there any way to solve this problem？The Crow framework seems unable to strictly follow the order of HTTP requests.
