SEND_AS_IS:DECHUNK_OPTION_IS_OFF

originated by    
mod_gzip_sendfile2

meaning
A Transfer-Encoding: chunked was detectet, but in the configuration 
mod_gzip has not been allowed to remove this encoding (i. e. collect all 
chunks and join them to one packet, whose content would then be 
compressable). The directive mod_gzip_dechunk Yes would have allowed 
mod_gzip to compress this request.
