Hi Bill,
Thank you for the warning as I was not aware.
If I can figure out how to use it to POST updates to my embedded device, for
example to set a new static IP from a simple web page, I think I will have what
I need. So far it appears that CGI only supports GET. The SSI includes work
well enough though for displaying device status on a web page.
I found this searching for 0x20000000:
/* If the data is being read from a buffer in RAM, we need to copy it
* into the PCB. If it's in flash, however, we can avoid the copy since
* the data is obviously not going to be overwritten during the life
* of the connection.
*/
err = tcp_write(pcb, hs->file, len, (hs->file < (char *)0x20000000)
? 0 : 1);
Thanks again,
-Ed

Be careful of the system dependency that is hard coded in the source code about
the location of flash and RAM. Search for 0x20000000.
