Just to answer this specific question: the WARC plays back somewhat slowly, but not unreasonably so, in Webrecorder Player; it's getting it to play from a server-based solution that's been more problematic... but as I noted in my previous message to the list, I now have a few ideas I can try. Fingers crossed that I'll have more to report before too long. 😊

Demain, have you used Webrecorder Player?  It allows playback of WARC, HAR, and ARC formats.  I'd be interested in how it performs for such a large website.  https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fwebrecorder%2Fwebrecorder-player&amp;data=02%7C01%7Cdemian.katz%40VILLANOVA.EDU%7Cdf19acda4290439dc73708d7c05c38df%7C765a8de5cf9444f09cafae5bf8cfa366%7C0%7C0%7C637189374634722689&amp;sdata=WHSe9tFU1qnUwwgObIUDdoRopvB83hQCjT9VBPxjwrI%3D&amp;reserved=0

Thanks, Carol. It was an old Drupal site, but unfortunately, at this point, the site is already gone, so the WARC is all I have -- but yes, I'm essentially looking for a way to unpack a WARC into the equivalent of the output of a giant wget operation. (We opted not to do things that way in the first place because some things needed to be changed incrementally as we went, and the WARC approach offered more flexibility in harvesting... but at the time, I had assumed that serving up a WARC was much simpler than it has so far turned out to be).

Hi Demian,

What kind of dynamic site is it? I've decommissioned old Drupal and Wordpress sites by essentially doing a big wget and generating a bunch of HTML pages. It's not perfect, and it depends on the site in question, but it has worked well enough. I wonder if that could serve as a Plan B for you.

Best wishes,

Carol
