Latex Beamer Class Remove Section from Headline

Question

I want to remove a few sections from the headline in beamer class. How do I remove them? I want them in my TOC but don't want them in my headline as that becomes too big then.

I tried this but this removes the entire headline.

%\setbeamertemplate{headline}{}

Use an empty optional argument for \section:

\documentclass{beamer}
\useoutertheme{miniframes}

\begin{document}

\begin{frame}
\frametitle{Outline}
\tableofcontents
\end{frame}

\section{Test Section on ToC  and on Headline}
\begin{frame}
test
\end{frame}

\section[]{Test Section on ToC not on Headline}
\begin{frame}
test
\end{frame}

\section{Another Test Section on ToC  and  on Headline}
\begin{frame}
test
\end{frame}

\end{document}

The resulting "Outline" frame showing both the ToC and the headline:
