I just want to create a firewall rule that matches all good bots and when URI path is ended with .exe. I check the document at https://developers.cloudflare.com/ruleset-engine/rules-language/expressions/
It seems that in the sample, the URI path will match if it is ended with /autodiscover.xml or /autodiscover.src. But I cannot find detailed document on whether and how regular expression can be used.
http.request.uri.path matches "/autodiscover\.(xml|src)$"
