Limit Access

This Spin application is designed to limit access to a given origin, until a configurable point in time has reached. Incoming requests hitting the Spin application before the desired point in time has been reached, won't be forwarded to the origin. Instead a configurable HTTP status code will be returned.

Application Configuration

The Spin application could be configured using settings specified in the following table:

Name Required Default Value Description
origin Yes none The desired origin url
block_until Yes none string representation of the UTC timestamp until inbound requests will be blocked
block_status_code No 404 Which HTTP status code should be sent during block period
track_blocked_requests No true Valid values are either true or false. If true, incoming requests are logged to a key value store
