alt Hacker NewsThey had some kind of intermediate representation of page renders that was efficiently cached on disk so that it made zero network requests on history navigation. I suspect this same approach also played a part in facilitating the fulltext history search feature I've also never seen in a browser since.
I'm guessing with the way web standards have evolved & become more complex this might actually be impossible to do today while remaining compliant - honestly give me non-compliance though.

Yeah, I don't know, I don't see how you can't pause execution and store the entire interpreter state and DOM somewhere. Maybe it's just that nobody cares enough to go through all the effort?

True! Came to post the same thing - one of my favourite feature of Opera Presto engine was how all the websites in your history was also "indexed" locally, so that you could do a simple keyword search on "History" to find the web page you wanted to re-visit. It was fast and accurate and made it a breeze to find any site in that you had browsed and was still cached, and it was an incredibly useful feature.
