Legality of keeping an offline cache of a website
I was hoping someone could shed some light on this for me:
1) is it legal to cache and store an entire website for offine browsing?
2)are there any caveats to this regarding subscription websites?
I have a 2 day free trial to a news website. I want to view it offline at my leisure, so I put a website cacheing program to work and store it all on my laptop/server. I might also want to keep the offline data for more than the 2 days. What are the legalities surrounding this?
