A maximum of 200 Custom Definition fields can be configured;
Field names are case-sensitive and must exactly match the original field names in HTTP actions;
Field names can be 1-100 characters long, beginning with a letter, and may include letters, numbers, and the '-' character, ending with a letter or a number;
Currently, only Site Acceleration Logs support adding custom definition fields.
