问题
I would like to understand more about Apache access log format.
This is an additional question to Understanding Apache's access log
Based on my log below,
27.111.34.139 - - [02/Sep/2015:03:50:47 +0800] "GET /&page=../../../../../../../../../../etc/passwd%00 HTTP/1.1" 404 248 "-" "Mozilla/9.0(X11; Linux x819_68) blog.inurl.com.br/eccbc87e4b5ce2fe28308fd9f2a7baf3.31 (KHTML, like Gecko) Chrome/26.0.1410.63 Safari/179.31" 70 0
As you can see that there are additional 70 & 0 at the end of the string.
What does 70 & 0 mean at the end of the string?
Does this occurred because of certain user-agent used or request or other specific parameters?
回答1:
70 is request size and 0 is the response size (in this case no response as the returned code is 404)
