Pass the pageId as a query string parameter.
PageParameters params = new PageParameters();
params.set("pageId", getPage().getPageId());
theUrlToTheReference = requestCycle.urlFor(yourResRef, params);
Then in the IResource (better extend AbstractResource) just read it from
the request parameters.
Storing the pageId in the session is not OK because the user may open two
different pages in separate tabs/windows and this will break.
