Good.

Maybe it's not an urgent feature of lwip, however I'll try to make a patch.


Another question. I have a .mp3 file in the filesystem. I have some 
problems with this file, because it seems it is requested two times from 
the browser. The second time the browser doesn't specificy 
Accept-encoding header, so I imagine it doesn't like a compressed .mp3 
file. It wants the uncompressed version (it's reasonable, because mp3 is 
already compressed).

Is there a msimple ethod to avoid makefsdata compressing certain non-SSI 
files, maybe based on extensions?
