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

[Artyom B. <art...@ya...>]

Can you give a hexdump of your echo command, because with -e there is still a redundend new line (after content length) so the content that is sent is actually bigger than it should be.

It seems that because you do not put '\r' than the Content-Length is ignored and not treated.

Also can give the response of the web server.
