Thank You Jifl, Your suggestion was very usefull. Problem resides in
http header, but it wasnt TAB character (probably it was only partial
problem), but content of header, especial first line containing
"HTTP/1.0 200 OK Content-type: text/html"
When I remove this line everything was ok. Newly generated page by NVU
editor works as well.
So it was more http protocol probem rather then lwip problem.
Thank You again Jifl !
