Hi,

I don't know if can be usefull, check www.dellapasqua.com/delphizlib

Inside unit you can found ZSendToBrowser, this routine inflate the stream
and send compressed content to browser using Zlib.

Perhaps you can found usefull use the same methods for ICS, embed zlib
objects with linker and then use directly without load DLL.

Regards,

Roberto

Oggetto: [twsocket] Adding gzip to HttpCli

Hello,

A contribution to compression with gzip and some answers to Maurizio's
questions :

It is a good idea to put the whole stuff in another unit.

a/ The site 'http://www.pipeboost.com/' works today for me in T_HttpCliGz.
If not, check if zlib.dll is well loaded.
Maurizio, if you want, I can send you my .exe

b/ FGzTime is used to know the time of reception and decompression. It can
help to choose a good compression level on the server side.
For example, I chose level 6 in a first time for one of my sites. After
tests, the level 1 was better...

c/ I chose to decompress at the end of reception, because in my xGzipStream
unit, the decompression is done for the whole stream after reading the
number of uncompressed bytes. This value is at the end of the stream.
We may decompress on the fly, but the units have to be rewritten. With the
actual RAM memory, I don't think it is necessary.

d/ I think that the RcvdStream can contain the compressed data during the
reception. So, RcvdCount can be used for a progress bar. At the end of
reception, I consider, according to Fran├žois's message of 09/05/2005 ("the
user has not to know if the received data were compressed or not") that
RcvdStream and RcvdCount are relative to uncompressed data.
I don't see why we have to keep the uncompressed data. Only my variable
GzContentLength keeps the compressed length.

e/ FRequestVer is set to 1.1, because some site don't compress if 1.0 is
sent.

f/ In my code, I have a GzAcceptEncoding boolean to disconnect compression
if necessary. It would be nice to keep it in case of problem with some
sites.

Sorry, I have not time today si answer other questions.

Regards

Xavier
