First, let’s explain how the website works.
1. Make a request from your browser saying “I want to see this page”
2. The Server returns OK or other “reply” = response
3. The content of the response shows the site in the browser
Have you ever seen a 404 not found error message? This is an example of the response returned by the server. On the contrary, what happens if it is normal? Request 200 is returned.
200 is normal,
301 is permanently moved,
302 is temporarily moved,
401 means authentication required,
403 means forbidden,
404 does not exist,
500 means server error.
With this kind of feeling, the response is returned from the server-side.
This series of exchanges is the access log.
How does the access log come back from the server? This slide shows an actual example. The first of 192.168.0.101 is IP represents the address.
Think of an IP address as an address for identifying individual computers when communicating over the Internet. The IP address is a character string that combines four numbers from 0 to 255. Just like 192.168.0.101 separated by 3 single periods. In theory, 256 of 4 square = 4294967296 (about 42 billion) IP, you can allocate the address. This is an IP address called IP V4 and is said to eventually change to something called IP v6. The number that can be assigned at this time will increase to 340 undecillion. This is a tremendous number of 10 raised to the 36th power.
Next are the date and time. The location of the index indicates the referenced URL. The 200 was a “normal” response. The part written as Windows means the OS, and the part written as Firefox is the browser.
