I don't know if this is a bug or just how it is handled by lwip. I'm
using html checkboxes and the POST method to update some LED's on a
avr32 board. If I send a post my header in lwip looks like this:
Host: 192.168.18.80
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.11)

Accept-Language: en-us,en;q=0.5

Connection: keep-alive
Referer: http://192.168.18.80/
Content-Type: application/x-www-form-urlencoded
Content-Length: 15
LED1=ON&LED2=ON
If i then change the second checkbox to not checked the header looks
like this:
Host: 192.168.18.80
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.11)

Content-Type: application/x-www-form-urlencoded
Content-Length: 7
LED1=ONN&LED2=ON
The content length says 7 but actually the content is the new post data
written over the old post data.
Should i report this as a bug or is this the way lwip should handle this
and i should always check the content length?
