Constant Summary

USED_IN_ROUTES =

We enable an ETag for every request matching the regex. To match a regex the path needs to match the following:

- Don't contain a reserved word (expect for the words used in the
  regex itself)
- Ending in `noteable/issue/<id>/notes` for the `issue_notes` route
- Ending in `issues/id`/realtime_changes` for the `issue_title` route

%w[noteable issue notes issues realtime_changes
commit pipelines merge_requests builds
new environments].freeze

Gitlab::PathRegex::ILLEGAL_PROJECT_PATH_WORDS - USED_IN_ROUTES

RESERVED_WORDS_REGEX =

Regexp.union(*RESERVED_WORDS.map(&Regexp.method(:escape)))
