Derive your own stream, probably best to be from TFilestream, but add a
header property or something. Then override the seek and read methods (I
think) to either seek into the file or into your header, and to read
appropriate data.

Subject: 回覆： Re: [twsocket] HTTP POST - SendStream With TMemoryStream
thanks F.P.
I See,
but if the file is more than 1 GB, That will cost my
too mush disk free space,I am confuse on this problem,
because I must add Form Field Value information on the
Head of the data and boundary end of data.it will be
work by ContentTypePost="multipart/form-data" mothod
post.

If you use TMemoryStream, then your 100MB of data is
loaded onto RAM which
can be slow. Use another kind of TStream, for
example a TFileStream which
store his data in a disk file instead of RAM.
