This is where Lift's FactoryMaker shines. You can modify the behavior of
stripComments on a request-by-request basis. You can have a snippet called
from your default template that tests the request and does:
LiftRules.stripComments.request.set(S.request.map(!_.isIE) openOr false)
But, as you point out, that means that CometActors will not get the right
settings... so you can set the rule on a session-by-session basis:
LiftRules.stripComments.request.set(S.request.map(!_.isIE) openOr false)
If that's not enough, you could also do the following in Boot.scala:
object shouldStripComments extends SessionVar(S.request.map(!_.isIE) openOr
false)
S.addAround(List(new LoanWrapper {
def apply[T](f: => T): T =
LiftRules.stripComments.doWith(shouldStripComments.is)(f)
}))
The above code wraps each request with access to the shouldStripComments
Session Variable.
The above vomit of different options is more for the benefit of those that
are confused by FactoryMaker and why it seems so complex... it's because it
offers a ton of different flexibility.
