# Forgejo's fixes: on Forgejo's paths, some fields skip the rules that refused
# ordinary Forgejo requests there. Forgejo is a fork of gitea. A hostname that
# gets Forgejo's fixes gets gitea's too, so this file holds only what Forgejo
# sends and gitea does not. Each exclusion runs with the request, before the
# rules it switches off, so this file is loaded before the Core Rule Set's
# rules. Each comment names a request the rule refused.

# Every rule below is skipped unless Inspect has set tx.app_forgejo. It sets it
# while SWW_WAF_APPS is unset, or lists forgejo for the request's hostname.
# The skip reaches only phase 1, so a rule of a later phase must check
# tx.app_forgejo itself.
