[wish] option to force 404 on any resources not in cdxj

[akavel]

Would it be possible to have an option in ipwb (via serviceWorker?) which would force any URLs not found in cdxj to fail/404? So that I could be sure that what I see is built without any external online resources, so I can check if it's readable as such; in other words: I could assess if it's "backed-up well enough for me".

As a workaround, I imagine I could possibly setup some proxy to force no connection to the Internet? or just turn off my WiFi?

(Somewhat related to #335)

The intent of the Reconstructive ServiceWorker is to prevent from any live leaks. This means that IPWB (that now uses Reconstructive) will make sure that non-local resources are served from the archive only and not from the live web. Currently, there are some implementation issues, but those are known bugs that will eventually be fixed.

@akavel I believe this is what already occurs. For example, if I

ipwb index ipwb/samples/warcs/5mementos.warc | ipwb replay

then curl -i http://localhost:5000/20140114100000/memento.us/, I get an HTTP 200 response, as that's one of the mementos available. However, if I change that command to curl -i http://localhost:5000/20140114100009/memento.us/ I get the following response:

Can you explain your idea a bit more?
