[lwip-users] httpd fails due to LWIP_HTTPD_REQ_BUFSIZE

[address@hidden]

I'm using lwip 2.0.3 with httpd and when submitting one of my webpage forms (using "type="submit"") the web browser complains lwip/httpd didn't send any data. 

Upon further investigation, the issue is in httpd.c:

#if LWIP_HTTPD_SUPPORT_REQUESTLIST

  clen = pbuf_clen(hs->req);

  if ((hs->req->tot_len <= LWIP_HTTPD_REQ_BUFSIZE) &&

    (clen <= LWIP_HTTPD_REQ_QUEUELEN)) {

hs->req->tot_len is longer than LWIP_HTTPD_REQ_BUFSIZE, which is 1023 because of:

#define LWIP_HTTPD_MAX_REQ_LENGTH           LWIP_MIN(1023, (LWIP_HTTPD_REQ_QUEUELEN * PBUF_POOL_BUFSIZE))

I tried increasing LWIP_HTTPD_MAX_REQ_LENGTH  to a higher value, but it caused an exception. What is the proper way to deal with this?
