CSS loading

The css-load extension checks that a client requests a CSS resource from BotStopper. The challenge page imports a test route. BotStopper checks that the client requests that route before it accepts the challenge.

Configuration

Add css-load to the extensions list in an existing challenge definition:

thresholds:
  - name: mild-suspicion
    expression:
      all:
        - weight > 0
        - weight < 10
    action: CHALLENGE
    challenge:
      algorithm: fast
      difficulty: 2
      report_as: 2
      extensions:
        - css-load

This example adds the extension to the fast challenge. Refer to thresholds for challenge selection and expressions for expression syntax.
