"access analysis: When accessing by"Hypertext Transfer Protocol without a Referer intelligence, the access analysis intelligence of "Hypertext Transfer Protocol-REFERER" which shows from which page it has flown can be sent to a server. Browsers, such as IE, have sent this intelligence mostly. If it was looking at the access log of the WWW server, the access to which the "Hypertext Transfer Protocol-REFERER" is not sent will have noticed a certain thing considerably. When inputting URL into a direct-address bar and flying, an intelligence does not have "Hypertext Transfer Protocol-REFERER", but it does not seem to see and meet from a rate. Seemingly it is ordinary IE when "USER-AGENT" which shows which browser is used is seen. Since the keyword block ? appeared, if "a REFERER block" is asked up about an access analysis at Google,Seemingly, he is trying not to send the "Hypertext Transfer Protocol-REFERER" intelligence, if "Norton Internet Security" is used. Seemingly, it can set up into a site seemingly send this intelligence only when accessing to a specific site as there is also a place which cannot be accessed well if there is "no Hypertext Transfer Protocol-REFERER."

Access analysis "whether is known about the access analysis": The functionality of the URL channel which can investigate a specific page or the number of accesses for every holder was introduced into Google AdSense which investigates the number of accesses for every specific page. [ 8 ] It enabled it to investigate the number of accesses to a specific page, and the number of accesses from a specific page for every time that it should be influenced up by this. A specification of a page is inputted by URL. If it is the specification to a holder like AdSense, the access analysis not only a specific page but below a holder will be conducted collectively. Possible instead of URL also at the regular expression which specifies URL. At this time, a regular expression is surrounded by / (backslash). For example, if it is /\.htm/, an extension will analyze only the access to the file of .htm. A specification of time is every hour or day by day [ 1 ].
