Hi there,

got an exception doing that

1) running a gws (as .java on
this mail)
2) refresh quickly at http://127.0.0.1:6666/ using firefox
for 10-12 time
3) KABOOM :)

probably the GZIP
cause this problem (where probably -> for sure).
This only happen when
buffer to write is bigger than some min amount (??) probably there is a
limit for the compression

Best regards! :)
