server| a list of variable server variables. The following explanations are some of the most commonly used:
Http_referer. When someone links to the current page, the Http_referer header saves the user's source, for example, if you want to know how many users are visiting the site from Yahoo, you can use HTTP_ Referer to obtain such information.
http_user_agent. This header indicates the type of Web browser used by the user to access the site, and you can use this header to understand what kind of browser your main customer base is using.
remote_addr. This header includes the IP address of the visitor, which allows us to know the initial source of the visitor.
query_string. The query_string variable contains the parameters that follow the question mark after you enter the network address.
script_name. This variable contains the virtual path of the current active Server page, which may be used when making your own reference connection.
server_name. This variable contains the URL of the server.
path_translated. This variable contains the real address of the current active Server page.
Today's version of Internet Explorer (version 3.0 and 4.0) contains the following headers in the request.
http_ua_color. This header contains the number of colors the browser can display.
http_ua_cpu. This header contains the CPU model of the computer that is executing the browser.
http_ua_os. Refers to the operating system where the browser is located.
http_ua_pixels. Refers to the resolution of the computer used by the browser.

It would be better if someone added 5.0 to it!!
