Biblatex - How can I suppress some fields for multiple entry types?

Apparently the rules have to be defined on an per-type-basis so the answer is: not possible.

\AtEveryBibitem{%
\ifentrytype{book}{
    \clearfield{url}%
    \clearfield{urldate}%

\ifentrytype{incollection}{
    \clearfield{url}%
    \clearfield{urldate}%
    \clearfield{review}%
    \clearfield{series}%%
}{}
}

%%%%not working:
%%%\AtEveryBibitem{%
%%%\ifentrytype{book,collection,incollection}{%supresses the fields for those entrytypes
%%% \clearfield{url}%
%%% \clearfield{urldate}%
%%% \clearfield{review}%
%%% \clearfield{series}%
%%%}{}%the other entrytypes are nore affected
%%%}

\usepackage{filecontents}

\begin{filecontents}{test-lit.bib}
@book{Abook,
  author = {AAAAbook, A.},
  year = {2001},
  title = {Alpha},
  url = {tex.stackexchange.com},
}
@online{Bonline,
  author = {BBBBonline, B.},
  year = {2002},
  title = {Bravo},
  url = {tex.stackexchange.com},
}
@collection{Ccollection,
    editor = {CCCCColletionEditor, C.},
    year = {2002},
    title = {Charlie},
    url = {tex.stackexchange.com},
}
@incollection{Dincollection,
    author = {DDDDincollection, D.},
    year = {2002},
    crossref = {Ccollection},
    title = {Delta},
    url = {tex.stackexchange.com},
}
\end{filecontents}

\addbibresource{test-lit.bib}

\nocite{*}

\listfiles

\begin{document}

Abc.

\printbibliography

\end{document}

\ifentrytype{book,collection,incollection}{%supresses the fields for those entrytypes
\clearfield{url}%
\clearfield{urldate}%
\clearfield{review}%
\clearfield{series}%
}{}%the other entrytypes are nore affected

UPDATE: as the other answer tells us, \ifentrytype only works with ONE entrytype as its argument.
