// This is the list of data reduction proxy bypass event types and their values.
// For the enum values, include the file
// "components/data_reduction_proxy/core/common/data_reduction_proxy_headers.h".
//
// Here we define the values using a macro BYPASS_EVENT_TYPE, so it can be
// expanded differently in some places (for example, to automatically
// map a bypass type value to its symbolic name). As such, new values must be
// appended and cannot be inserted in the middle as there are instances where
// we will load data between different builds.

// Bypass due to explicit instruction for the current request.
