I have a code like below: using HTTP: @register, Response, handle const HEADERS = ["Content-Type" =\> "application/json"] bench\_start\_handler(req) = nothing hoge\_handler(req, body) = ... # return JSON string ... # another handler body bench\_end\_handler(req) = nothing const router = HTTP.Router() @register(router, "GET", "/bench\_start", bench\_start\_handler) @register(router, "POST", "/hoge"…

That goes with threading, not sure if want to go there, but some of the concepts might work well for the single thread case.
