Downside of TGZFileStream is that it only works with a file. If you only
need to decompress an odd page than that is fine. If you have a lot of
packets with variable sizes to compress/decompress then using intermediate
files slows things down quite a lot. In my case the application runs as a
library which also adds file system access complications. Hence the modified
paszlib library I mentioned earlier which does everything in memory.
TDecompressionstream and TCompressionstream have a SkipHeader parameter which
should enable you to compress/decompress gzip streams in memory; You just have
to take care of the header blocks yourself.
The paszlib library distributed with FPC is the nommsi paszlib library.
So if you have a unit with a convenience function/class, please consider donating
it to FPC.

Hello,
Does anyone know if zlib will successfully uncompress the data
received in "gzip" method from an HTTP server? I think gzip is the
same as zlib, but I'm not sure =o
gzip adds an additional header, but this can be read with the TGZFileStream
class from zstream.
Or else which Pascal bindings or Pascal uncompressor should be used?
zstream should be able to handle it.
Michael.
