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

HTTPCli.RcvdStream:=TMemoryStream.Create;
Then, in the OnRequestDone, 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).RcvdStream);
//Use StringList...
Stringlist.Free;
You are getting the access violation because you didnt allocate the stream 
before starting the request.

I don't really know what to do with TMemoryStream... i need TStringList ...
the site isn't that big, so it should be any problem... But i still don't
know how do i convert the recived stream to TStringList... ;-(

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.
