The default client timeout is too small to be sure to always wait end of slow clients (the last 2 clients use a delay to send their request). But it cannot be increased because it will slow down the regtest execution. So a dedicated frontend with a higher client timeout has been added. This frontend is used by "slow" clients. The other one is used for normal requests.

|

# thanks to "http-buffer-request". If this was the case, c2 client
