Both Firefox & IE supports decompression method

HTTP_ACCEPT_ENCODING=gzip,deflate 


By this way, the file can be kept around few
kilobytes
in the server and delivered easily. I wonder, why
such... simple issue went un-noticed to everyone
for
years... 


Dear bipin, 

Good observation ! Works for me on mozilla 1.7.5
also on win2k sp4 and all
other patches 

But Is this not a small issue that can happen to
kind of data? .... 3.5 mb
of data as a pic image or a pic with very high width
will also do the same
and there will certainly be more of such doss` 
that was one of an old advisory! but, i think this
issue has been fixed.

yap, that's why I specifically mentioned the...
HTTP_ACCEPT_ENCODING=gzip,deflate  (O;
Moreover, when the file is being download from a
remote server and being loded, the DoS has already
been triggered! I'd only tested it on Mozilla
Browser(Linux) and falsely concluded Mozilla isn't
pron to this bug!

Can anyone test it for OPERA as well?
regard,
bipin
