User Experience (Response)

Applies To:

HTTP LargeThis platform has been optimized to cache and deliver static content (e.g., HTML, CSS, JavaScript, ISO, multimedia, and software downloads, etc.) over HTTP or HTTPS.

HTTP SmallLegacy. If you are currently serving traffic over this platform, then you may continue to do so. However, we recommend that you serve your traffic over our more robust HTTP Large platform.

ADNThe Application Delivery Network platform has been optimized to deliver dynamic content (e.g., login credentials, account information, etc.) over HTTP or HTTPS. Typically, user-specific and database-driven content are served over this platform.

WAFWeb Application Firewall is designed to secure site traffic against DDoS and application layer attacks. It also filters unwanted traffic by enforcing a custom delivery profile and whitelists, access list, and blacklists. Finally, it controls the flow of requests to your applications.

A Security Application Manager configuration determines the action that will take place when a threat is identified or a request exceeds a rate limit.

Threats

A Security Application Manager configuration identifies a traffic profile, the rules that determine how that traffic will be screened, and the enforcement action that will take place when a threat is identified. This enforcement action is defined when you assign an access rule or managed to a Security Application Manager configuration. The user experience for each possible configuration is described below.

Configuration	Description
Alert	Our service treats the request as if it had not been screened. The client will be unaware that the request was screened by WAF.
Block	The user experience for requests blocked by WAF is described below. The user will receive a 403 Forbidden instead of the requested asset. The response for the blocked request will include an additional response header. The name of this response header is defined by the corresponding rule's Response Header Name option. This response header will be set to 403. Default WAF response header name/value: X-EC-Security-Audit: 403
Custom Response	Our service provides a custom response to identified threats. This custom response is defined within a Security Application Manager configuration when setting up access rules and managed rules. It defines the response headers, body, and status code that will be sent to the user.

Our service provides a custom response to identified threats. This custom response is defined within a Security Application Manager configuration when setting up access rules and managed rules. It defines the response headers, body, and status code that will be sent to the user.

Rate Limiting

Upon exceeding a rate limit, your Security Application Manager configuration determines the action that will be applied to eligible requests. The user experience for each possible configuration is described below.

Configuration	Description
Alert Only	Alerts do not alter the user experience. Our service treats the request as if it had not exceeded the rate limit.
Custom Response	Our service provides a custom response to rate limited requests. This custom response is defined within a Security Application Manager configuration when setting up rate rules. It defines the response headers, body, and status code that will be sent to the user.
Drop Request	Our service sends a 503 Service Unavailable response with a Retry-After header to rate limited requests.
Redirect (HTTP 302)	Our service redirects rate limited requests to a predefined URL. The client will receive the response for the resource located at that URL and a 302 Found.
