On June 22, 2000, OMB issued this Memorandum, which referred to the earlier OMB Memorandum M-99-18, and the need for agencies to comply with this earlier guidance. However, the June 22, 2000, memorandum provided additional guidance relating to the collection of information by federal websites using cookies.
A September 5, 2000 letter from OMB to the Department of Commerce further clarified that “persistent” cookies, which remain on a user’s computer for varying lengths of time (from hours to years), are not allowed unless these four specific conditions are met. “Session” cookies, which expire when the user exits the browser, are permitted.
Subsequent developments Edit
In 2003, the E-Government Act of 2002 privacy implementation guidance expanded the types of technologies included under these policies to include any tracking technology that lasted longer than a user’s one‐time visit to the website.
This Memorandum was rescinded by OMB Memorandum M-10-22.
