You got it precisely. Should be:
<map:match pattern="*.do">
<map:act type="auth-protect">
<map:parameter name="handler" value="myhandler"/>
<map:call function="main">
<map:parameter name="page" value="{../1}"/>
</map:call>
</map:act>
<map:redirect-to uri="login"/>
</map:match>
i.e. {../1} to get at the matcher rather than the action.
