What you are asking is mad mojo, and this is not really the place to ask
it. Also, it's not really a job for captive portal so much as an
auxiliary transparent proxy.
I don't think you grasp just how complex what you are asking is, though.
I assume that you want something like a top frame with your content in
it on every page that a user visits. Would you have your URL at the top,
or that of the page that a person is visiting? Either way, it's trouble.
If you choose your URL, you have to prefix every page a person visits
with a JS to check window.location, and to redirect if it's not your
and get rid of it. 2. Other sites do the same thing, to make sure that
you're in their frameset. If a user hits one of these sites, you wind up
with an infinate loop.
If you want their URL, you've got more trouble. In that case, you have
to figure out all kinds of logistical issues with how to deal with
posting your own frameset, not killing other framesets, and making sure
not to stack your own framesets. It should be all but impossible without
JS, and is like to break URLs with target attributes set and all kinds
Before you get into this, consider the problems. After that, you'll have
to find a piece of software that either does what you need or can be
adapted to do so. At that point, you may have to come back here to
figure out how to integrate it into m0n0wall.
