Convert the received stream to a string list ? Arno told you:
AStream.Seek(0, sofromBeginning);
StringList.LoadFromStream(AStream);
But if you want to convert to a string list for analysis, it is probably
not the most efficient way
to do that. You should probably use a TMemoryStream and direction use the
data in memory :
var
P : PChar; // Will point to HTML data (or whatever data you received)
N : Integer; // Will contains the number of bytes
begin
P := PChar((THttpCli(Sender).RcvdStream as TMemoryStream).Memory);
N := THttpCli(Sender).RcvdStream.Size;
// Now you can use P and N to analyse the document received. Very
fast.
// Don't forget to free the stream when processing is done or you'll have
a memory leak.

Before you start your request (before the get) you need to assign the
receive stream:

;

Then, in the RequestDone, as has been explained, you have the rcvdstream
to read from:

var StringList: TStrings;

StringList:=TStringList.Create;
THTTPCli(Sender).RcvdStream.Seek(0,soBeginning);
StringList.LoadFromStream(THTTPCli(Sender).RcvdStr eam);
//Use StringList
Stringlist.Free;

You are getting the access violation because you didnt allocate the stream
before starting the request.

IMH a slightly better solution:

('');

// RequestDone event
StringList:=TStringList.Create;
StringList.Text:=TStringStream(THTTPCli(Sender).Rc vdStream).DataString;
//Use StringList
Stringlist.Free;

You are getting the access violation because you didnt allocate the

I'm sorry, but I strongly suggest that you learn Delphi by a far smaller
project before you start a multithreaded HTTP application.

BTW: This is not a Delphi tutorial list. Find out such basic things by
yourself. There's an online help, there's the big FAQ Google and there
are examples in your Delphi directory.

So this ruin everything semi-multithreading won't make its role
