While creating new rules (configuration rules, redirect rules) in Cloudflare, I needed to better understand the different fields and what value I should expect for each.
For example, whether the value of the
URI Query String field contains
For this, I selected the desired field from the dropdown menu, copied its full name from the “Expression Preview” section (for instance,
URI Query String becomes
http.request.uri.query), and searched for it on the Fields reference page in Cloudflare Docs. This page contains the full list of all available fields, including a description and an example value.
Hope it helps!
