Correctly understand the meaning of Traceback

Traceback is an important feature of the blog, however, due to traceback ambiguity caused many people do not really understand the use of traceback.

Traceback Ping is widely used in the blog system, in short, trackback is a way to communicate with each other in the Web site. For example, when you read a journal and want to write down your thoughts about it, you can write the new journal content on your blog. Then send a trackback to the original log. In this way, there is a link to the log in your blog below the original article, so the discussion of the same topic can be limited to one blog.

Traceback in China are mostly translated as "trackbacks", so that a great misunderstanding, many people will trackback understand as a reference address, I often received some inexplicable traceback, point past a look, originally just reproduced my article just, This is clearly an error in understanding and using the trackback, mistaking it for the meaning of "reference", which in fact trackback is not used for.

Give an example to illustrate. For example, you read an article of interest in my Moonlight blog, you have some ideas about this article, but if you write more words, usually more than the comment word limit, this time you can write in your own blog, this brings the benefit of the word is not limited, but also conducive to future maintenance, But how do you tell me you wrote this comment? If there is no traceback, you can only reply to your link URL address in the comments, but with Trackback Ping, no longer need to do so, you just through the trackback of your article information Ping over, My blog system will automatically receive from other blog site Trackback Ping, and publish it to the article, this is the correct use of trackback, unfortunately, most bloggers in the country has not yet formed the habit of using trackback correctly.

Trackback in China This special environment will also produce some problems, that is trackback Spam (garbage Reference), in fact, the same as the nature of spam, but because of the characteristics of trackback, but also difficult to follow the garbage message method to deal with.

The trackback protocol itself is simple and has no validation capabilities. As long as you send a legitimate ping over, the program must be received. As long as you find the program file that performs this function and find each article to refer to the law of the address can be sent to a large number of trackback Spam (garbage Reference). At present Z-blog Trackback is very regular, very easy to be spam, I can do only use nofollow tag to deal with, cannot solve the fundamental problem.

Of course, it is not difficult to solve the problem, is that we generate trackback address, add an encrypted checksum code, such as for the article ID a special MD5 summary, the irregular string in the trackback address, so if someone sent over the ping in the checksum error, You can think of it as a spam, otherwise you'll think it's the right ping. This is probably one of the reasons why the URLs of MSN Spaces look particularly strange, and if I have time later, I will write some specific Z-blog implementation code to complete this function.
