Hi Sergio, with the latest versions of TsgcWebSocketHTTPServer, files assigned to Contentstream are no longer released. In fact, the DoHTTP2Response function sets the property to nil and doesn't free it.

procedure TsgcWSConnection_Base_HTTP2.DoHTTP2Response(const aRequest
: TIdHTTPRequestInfo; const aResponse: TIdHTTPResponseInfo;
const aLinks: TStrings; aStreamIdentifierRequest: Integer;
aStreamIdentifierPush: Integer = 0);
...
...
...
// ... send data
if not oHeader.EndStream then
begin
oData := HTTP2FrameWrite.Frame_Data;
oData.Clear;
oData.StreamIdentifierRequest := aStreamIdentifierRequest;
oData.StreamIdentifier := oHeader.StreamIdentifier;
oStream := nil;
if aResponse.ContentText <> '' then
oStream := TStringStream.Create(aResponse.ContentText{$IFDEF D2010},
CharsetToCodePage(aResponse.CharSet){$ENDIF})
else if aResponse.ContentStream <> nil then
oStream := aResponse.ContentStream;
Try
oData.SetStream(oStream);
oData.WriteBytes;
Finally
aResponse.ContentStream := nil; <----------------
End;
end;

Consequently, the file remains locked for some functions (rename or delete). Is there a way to have it free the resource instead of setting it to nil?
Alternatively, how can I determine when the handle can be freed?
