D2W creates stateful pages. There is already a cookie set for the session. If
you store what state you need on the session, then you can retrieve it from
there easily.
If you are going to somehow lose the session, setting a cookie is probably not
a robust enough way to handle things. Example: User changes email from
computer… “We sent you an email! Please open it and click the confirmation
link”… How do you know the user won’t pick up their smartphone and check email
from there? Or check in mail.app which pops open safari instead of chrome when
they click. Or any other number of scenarios where the browser changes. In that
case, you either need to set your state in the DB and pick it up by uuid when
they click the link, or encrypt the state and store it in the link itself if it
is a small amount of state.
To answer your question, you can probably set a cookie using some kind of
global cookie store and notifications without needing to modify anything
happening with D2W. Listen for WORequestHandler.DidHandleRequestNotification,
then
public void didHandleRequest(NSNotification n) {
WOContext context = (WOContext)n.object();
WOCookie cookie = ...
context.response.addCookie(cookie);
...
}
