Kroning has asked for the wisdom of the Perl Monks concerning the following question:
I have some packet from app that looks like "ec bd ... 00 00 ff ff" which I am trying to decode.
From what I have found, it looks like "00 00 ff ff" is a Z_SYNC_FLUSH of deflate (zlib).
I tried to reproduce it on Compress::Raw::Zlib, Compress::Zlib and some others. But the ending pattern was "00 ff 00 ff". Am I missing something?
