If I understand this correctly, you are not sending or receiving files in
chunks. On the HTTP protocol level I mean. You are solely interested in
passing a TFileStream instead of a TMemoryStream. So if the server you are
connecting to limits the file upload to fe. 10 MB, then that's it: 10 MB is
your limit. If you are using a slow line and the file you receive is sent by
a PHP script that has a timeout of say 30 secs, then you are stuck with a
low receive limit. My understanding of your original question of chuncked
transfer was that you were trying to address these issues.

Objet : [Synalist] RE : THTTPSend - posting and receiving big files
Ok,
I wrote my own descendant:
TMyHTTPSend = class(THTTPSend)
private
function MyReadUnknown(AFile: TFileStream): Boolean;
function MyReadIdentity(AFile: TFileStream; Size: Integer): Boolean;
function MyReadChunked(AFile: TFileStream): Boolean;
public
function UploadFile(const Method, URL, AFileName: string): Boolean;
function DownloadFile(const Method, URL, ADestFileName: string):
Boolean;
end;
Which use code from HTTPMethod but instead of
FSock.SendBuffer(Document.Memory) it uses FSock.SendStream(f) and
FSock.ReadStream(f) where "f" is TFileStream and it works like a charm :D .
Great that all methods and local variables are in protected section. Now I
can upload and download very big files without loading them to memory and
with all THTTPSend functionality (OnHeartBeat, OnStatus etc)
Regards
