Re: [lwip-users] LWIP 1.4.1 uploading problem

@Simon: oops, didn't take my pills and Z80assembly-induced dyslexia 
jumped in... ;^) I meant "server", my mistake.
@Noam: My server does have POST, multipart (beginning) and login 
(plain). We could join forces and have a good server in github or 
wherever, I have lots of ideas but my development time has shifted to 
more mundane and somehow paid projects. At the time I asked, no one 
seemed to show interest. I forked from the "official" server to avoid 
supporting the old CGI and SSI structure, which I didn't (don't) like 
(at all)(matter of personal taste), and my brain can't keep such a level 
of complexity. My CGI scheme is loosely based on the idea behind the 
Rabbit (Z-World), which I've been using for a long time.
@Szabolcs: you can (almost) always capture only client and server 
traffic, and post reduced pieces of code where we can see how you are 
using the stack.
Example for a TCP receive callback:
static err_t myrecv(void *arg, struct tcp_pcb* pcb, struct pbuf *p, 
err_t err)
{
        if ((p == NULL) || (err != ERR_OK)){
                ...
                myclose(pcb);
                return ERR_OK;
        }
        ...
        read p data
        do something with that
        ...
        tcp_recved(pcb, p->tot_len); <--- handle TCP window
        pbuf_free(p);                   <--- free receive buffer
        ...
        return ERR_OK;
}

However, it's your call.
I can't help with the server post cgi callbacks, I changed that scheme 
in my server and didn't get to use the "official" one. However, 
somebody, somewhere, has to do what Simon said and I marked on the 
pseudocode for you; look for it.
