If you want to decode the data manually, then look at the DecompressGZipStream() method of the TIdCompressorZLib component, or the TDecompressionStream class or Indy/DecompressStream() functions in the IdZLib.pas unit.

I already tested them, they not working. And the unit name is IdZLibCompressorBase.pas – jmp Dec 22 '11 at 02:57
I found the problem why it's not working, i forgot to set: my_stream.Position := 0; – jmp Dec 22 '11 at 03:47

`TIdCompressorZLib` derives from `TIdZLibCompressorBase`. As its name suggests, `TIdZLibCompressorBase` is a base class, don't use it by itself. – Remy Lebeau Dec 22 '11 at 05:58
