Remove or rewrite subresource integrity hashes #149

Open vincentbernat opened 7 years ago

vincentbernat commented 7 years ago

Hey!

Some sites are using subresource integrity to ensure CDN do not alter the linked resources (notably JS and CSS). Unfortunately, when such a page is archived, CSS and JS are altered to add some comments. This makes SRI hashes inexact and browsers won't load them. See this example.

Just ran into this myself with some Github pages:

It seems to be intermittent (maybe they're doing a partial rollout?) but it's definitely affected some crawls I know of.
