If you'd look at the current version of TRequest.InitPostVars, you'd 
know why it is empty ;)

=== source begin ===

procedure TRequest.InitPostVars;

Var
   M  : TCapacityStream;
   Cl : Integer;
   CT : String;

begin
{$ifdef CGIDEBUG}
   SendMethodEnter('InitPostVars');
{$endif}
   CL:=ContentLength;
   if CL<>0 then
     begin
     M:=TCapacityStream.Create;
     Try
       if CL<>0 then
         begin
         M.Capacity:=Cl;
         M.WriteBuffer(Content[1], Cl);
         end;
       M.Position:=0;
       CT:=ContentType;
       if Pos('MULTIPART/FORM-DATA',Uppercase(CT))<>0 then
         ProcessMultiPart(M,CT, ContentFields)
       else if Pos('APPLICATION/X-WWW-FORM-URLENCODED',Uppercase(CT))<>0 
then
         ProcessUrlEncoded(M, ContentFields)
     finally
      M.Free;
     end;
     end;
{$ifdef CGIDEBUG}
   SendMethodExit('InitPostVars');
{$endif}
         end;

=== source end ===

So it seems that you MUST set the contenttype either to 
MULTIPART/FORM-DATA or APPLICATION/X-WWW-FORM-URLENCODED.

Maybe TRequest should be extended by something like an "unknown content 
type handler"...
