In the process of SEO to view the IIS log is a very important thing, especially when the page made a relatively large changes, through the log detection, you can find a lot of interesting questions. Now the space provides the function of the log query, and the log is generally stored in the root directory of the site log, Wwwlog, LogFiles, and other similar directories, through the download of similar files extracted can be used Notepad to view.

Below I intercept a section of code for analysis.

2010-07-24 02:20:57 w3svc133 221.231.137.66 get http://zuyupen5.com/index.html–80–123.125.66.111 baiduspider+ (+http ://www.baidu.com/search/spider.htm) 200 0 64 0

2010-07-24 02:20:57 Spider's Access time

221.231.137.66 Access IP Address

W3SVC133 Machine code

Get Request method

/index.html Requested URL

80 Server port number

123.125.66.111 Server IP

Baiduspider Baidu Spider

200 0 64 0 200 to indicate the success of the request, 64 means that Baidu's crawling of the page is not fully read finished, in the process of crawling abandoned, belonging to an error code, and the last data is 0, then the crawl page size byte is 0.

200 0 64 status codes are: Sc-status (protocol status, 200 in this connection success) Sc-substatus (Protocol sub State) Sc-win32-status (Win32 status code, 64 is the specified network name is not available

Look at the second one:

2010-07-24 12:37:39 w3svc133 221.231.137.66 get http://zero07.cn/501.html-80–203.208.60.79 mozilla/5.0+ (compatible;+ googlebot/2.1;++http://www.google.com/bot.html) 200 0 0 6503

/501.html Requested URL

Compatible refers to compatibility

Googlebot Google Robot

200 0 0 6503 requests succeeded and downloaded 6503 bytes of data.

Generally we just look at Baidu and Google Spider can be, the other way, no example. Below I enumerate the common HTTP status codes:

1XX (temporary response); 2xx (success); 3xx (redirected); 4xx (request error); 5xx (server error);

200– Server successfully returned Web page

301-Permanent Resource redirection

302-Temporary resource redirection

304-The page is changed after the last get

403-The server has requested, but not yet executed

404-Request Error or request failed

505-http Version not supported

Do not need too much, the above HTTP status code can read well, other status code is less common, so do not remember, use the time you find in the search engine can be.
