There is no direct counterpart for \ifpdf but indirectly one can
employ an instruction  similar to

   \ifx \HCode\UnDefined \else ... \fi

However, private configuration files 

   http://www.cse.ohio-state.edu/~gurari/TeX4ht/mn3.html#QQ1-3-13

offer cleaner approaches.  For instance, the definition of \foo in

    \documentclass{article}
        \def\foo{...}
    \begin{document}
       \foo
    \end{document}

can be redefined in a private configuration file for a desirable
behavior under tex4ht.

How are the page breaks requested?  Those that are automatically
created by the native tex engine are meaningless for hypertext output.
