Content-Length header always zero?

[disleyland]

in migrating to Julia 1+, i find Mux always serves headers with content-length set to zero (which means my download progress widgets are broken). Is there a new setting to re-enable Mux (or HTTP.jl) to send the computed file size in the headers?

after some research and testing figured it out. seems we have to manually configure these things now in mux.

using Mux, HttpCommon,JSON

function mycustomheaders(str)
headers = HttpCommon.headers();
headers["Content-Length"] = JSON.json(sizeof(str)); #note use sizeof not length!
Dict(:headers => headers,:body=> str);
end

function testfunc(req)
return "some big file to test content length here"
end

@app service = (
Mux.defaults,
page("/demo", req -> mycustomheaders(testfunc(req))),
Mux.notfound()
)

serve(service,7777)
