The Web Accessibility Initiative site provides instructions for other browsers and operating systems.

For site management, information is collected for statistical purposes. This U.S. Government computer system uses software programs to create summary statistics, which are used for such purposes as assessing what information is of most and least interest, determining technical design specifications, and identifying system performance or problem areas. Below is an example of the information collected based on a standard request for a World Wide Web document:

• xxx.yyy.com (or 123.123.23.12) -- this is the host name (or Internet protocol (IP) address) associated with the requester (you as the visitor). In this case, the requester is coming from the xxx.yyy.net address. Depending on the requester's method of network connection, the host name (or IP address) may or may not identify the user's specific computer. Connections via many Internet Service Providers (ISP) assign different IP addresses for each session, or only connect to the Internet via proxy servers, so the host name may only identify the ISP. The host name (or IP address) may identify a specific computer if that computer has a fixed IP address.
• [28/Jan/2008:00:00:01 -0500] -- this is the date and time of the request
• "GET /Defense/news/nr012708.html HTTP/1.0" -- this is the location of the requested file
• 200 -- this is the status code - 200 is OK - the request was filled
• 16704 -- this is the size of the requested file in bytes
• Mozilla 3.0 -- this identifies the type of browser software used to access the page, which indicates what design parameters to use in constructing the pages
• www.google.com -- this indicates the last site the person visited, which indicates how people find the requested file.

Requests for other types of documents use similar information. Unless otherwise stated, no personally-identifiable information is collected.

For site security purposes and to ensure that this service remains available to all users, software programs are employed to monitor network traffic to identify unauthorized attempts to upload or change information, or otherwise cause damage.

Except for authorized law enforcement investigations and national security purposes, no other attempts are made to identify individual users or their usage habits beyond DoD websites. Raw data logs are used for no other purposes and are scheduled for regular destruction in accordance with National Archives and Records Administration Guidelines*. All data collection activities are in strict accordance with DoD Directive 5240.01.

Web measurement and customization technologies (WMCT) may be used on this site to remember your online interactions, to conduct measurement and analysis of usage, or to customize your experience. The Department of Defense does not use the information associated with WMCT to track individual user activity on the Internet outside of Defense Department websites, nor does it share the data obtained through such technologies, without your explicit consent, with other departments or agencies. The Department of Defense does not keep a database of information obtained from the use of WMCT. General instructions for how you may opt out of some of the most commonly used WMCT is available at http://www.usa.gov/optout_instructions.shtml.

Unauthorized attempts to upload information or change information on this site are strictly prohibited and may be punishable under the Computer Fraud and Abuse Act of 1987 and the National Information Infrastructure Protection Act (18 U.S.C. § 1030).
