Re: [Cppcms-users] 404 not found with valid URL and POST Request

Sorry my echo has an alias on -e ,  so actually my previous are to read like echo -e  ,  and as said I first discover the problem in my python script that use httplib to generate the http request.

Allan,

You are missing something important:

$ echo echo 'POST /users/register-new_treat HTTP/1.1\r\nHost: en.tatolocal:8080\r\nAccept-Encoding: identity\nContent-Length: 13\r\ent-Type: application/x-www-form-urlencoded\r\n\r\nusername=toto' | hexdump -C

$

echo '\r\n' gives output

"\r\n" (4 bytes "\" "r" "\" "n")

And not 2 bytes CR-LF bytes \x13\x10
