Partly.  I knew that most browsers accepted gzip but not zlib content 
encoding.  However I thought that such a browser would include only 
"gzip" in its "Accept-Encoding" header.  What I think you're saying is 
that some browsers include "deflate" in the header, but are actually 
expecting a raw deflate stream instead of a zlib stream!  (This may be 
related to the poor naming of the "deflate" content encoding.  They 
probably should have called it "zlib".)
