Filter out hash urls

[giancarloaf]

I wonder should we filter out hash urls as well?

e.g. https://www.example.com/index.html#1234.1234

Seems it's about extracting file extension from requests URL.

Interestingly, I just don't see URLs with hash (in sampled data):

SELECT
  url,
  JSON_VALUE(summary, "$.ext")
FROM `httparchive.all.requests` TABLESAMPLE SYSTEM (1 PERCENT)
WHERE date = "2024-09-01"
  AND STRPOS(url, "#") > 0

@pmeenan you think we need to do anything here?
