This follows on from python/psf-salt#287, where we have added
Surrogate-Keyheaders to all language-version pairs. These are consumed internally by Fastly and can be used to purge an entire set of pages at once, rather than doing so per-page.I've tested using
curlto send the requests manually and it seems to work -- we get a cache hit, purge the surrogate key, and then get a cache miss.This should also marginally improve build times, but I think the simplification stands alone as a value proposition.
