Re: [lwip-users] Post messages with the httpd.c example

[Adam Baron]

Hello,

small MTU  can be overridden  by TCP_MSS I believe. The default 536 is very small for POST indeed.

The post parsing in the http code has couple problems.  Most of the time it will not cause issues.

First it assume the first packet includes the entire POST header.  With small MTU size this might not happen. 

Second it adds a null terminator at the end of the POST header before calling httpd_post_begin().  This is a minor issue and might be considered a design intent.

My observation is that httpd_post_receive_data is called for each received
packet until content_len for this connection is reached. Then the
httpd_post_finished is called for application to finalize.
