I've spoken too early!
when I set LWIP_HTTPD_SSI and LWIP_HTTPD_CGI to 1, I ha ve the same problem
than before...

thanks Simon
when I define HTTP_IS_DATA_VOLATILE(hs) to 1 it works, but the checksums is
disable. so the problem seems to be in a wrong checksums. what I have to check?

I'm not sure that the problem relies on lwip port, since with previous version
of httpd everything work fine (at least with page without frames)
It still seems like an issue in your port as normally, application changes
should not lead to invalid checksums or even skipped TCP segno's. You could try
to define HTTP_IS_DATA_VOLATILE(hs) to 1 so that data is always copied in to
PBUF_RAM pbufs for sending. But while (invalidly) using no-copy might lead to
invalid checksums, skipped segno's should be totally independent of this
setting (since TCP headers are always saved in PBUF_RAM pbufs).
