Call continuations from flow instead of sitemap

[Leszek Gawron]

I have this snipped in one of my .js files :

var user = null;
function main( action ) {
        cocoon.response.setHeader( "Expires", "-1" );
        cocoon.response.setHeader( "Cache-Control", "no-cache" );
        cocoon.response.setHeader( "Pragma", "no-cache" );
        
        if ( user == null ) {
                loginInternal();
        }

        invoke( action );
}

This is based on the linotype sample. I add some headers to every flow
invocation response to make the IE not cache the content. It works fine but I
have a problem with continuations. This url:

http://ouzo/nTer/310b3f485d5a0c0a243e3011632a138d38357c38.continue

is still cached. So I need to set cache control headers for these urls too. 
I know I can make it in sitemap (via actions) but I would like to have ALL
logic in my flow and use sitemap.xmap only for view rendering. 

How can I achieve something like this (pseudo-code of course):

var user = null;
function main( action ) {
        cocoon.response.setHeader( "Expires", "-1" );
        cocoon.response.setHeader( "Cache-Control", "no-cache" );
        cocoon.response.setHeader( "Pragma", "no-cache" );
        
        if ( user == null ) {
                loginInternal();
        }

        if ( isFunction( action ) )
                invoke( action );
        else if ( isContinuation( action ) )
                runContinuation( action );
}

function isFunction( action ) {
        return ( this[ action ] != undefined );
}

function isContinuation( action ) {
        return endsWith( action, ".continue" );
}

function runContinuation( action ) {
        // ????????????
}

        lg
