URL rewriting-I think

 

 

 

 

 

 

 

1. URL Builder URL: (do not write regular expressions, which can be generated using the following tools !)

Http://seohelper.cn/tools/urlrewrite

 

Generate two different URL rules based on the written URL (that is, regular expression)

 

 

2. URL rewriting --- Glossary:

The URL is intercepted by the server and parsed. The default rule is DDD. php? Id = 1 & page = 2, ?, & To identify.

 

You can use the. htaccess file in the web root directory to rewrite the file. The principle is that when you access the file in a URL format, you can rewrite the rule and translate it into DDD. php? Id = 1 & page = 2

The rewrite Mechanism acts as a translation function.

 

 

(Http://www.g4qq.com/user/id/2/) ----------> (rewrite mechanism translation) -----------> (http://www.g4qq.com/user.php? Id = 2)

 

 

The description of the. htaccess file is as follows:

Options + followsymlinks

Rewriteengine on

Rewriterule user-ID-(. *)/. html $ user. php? Id = $1

Rewriterule user/ID/(. *)/user. php? Id = $1

 

Rewriteengine on indicates that the rewrite function is enabled.

Rewriterule:

User-ID-(. *)/. html $ user. php? Id = $1 is a translation rule (regular expression)

User/ID/(. *)/user. php? Id = $1 is also a translation rule

 

If you use the rewrite rule rewriterule user-ID-(. *)/. html $ user. php? Id = $1, which can be accessed at http://www.g4qq.com/user-id-2.html,

Then the URL is intercepted, through the URL rewriting mechanism, converted to http://www.g4qq.com/user.php? Id = 2, which is then parsed by the default Apache rules. This is actually a spoofing,

In the final analysis, is it still converted into a http://www.g4qq.com/user.php? Id = 2.

 

 

3. If you still get confused here, perform the instance first.

 

Generally, all spaces support the rewrite function.

There is a. htaccess file and user. php file under the folder I sent. First, you log on to your blog URL. If your blog

There is a. htaccess file or a user. php file under the web root directory. Back up the files and pass them to the root directory of the website,

Access http://www.g4qq.com/user/id/2/,http://www.g4qq.com/user-id-2.html after completion

Of course, you need to replace g4qq with your website directory. You will find that both websites can be accessed and get the same result. This is the URL rewriting.

Is a kind of deception, their results are the same, are http://www.g4qq.com/user.php? Id = 2.

 

 

 

Note:

The code in the user. php file is simple:

<? PHP

$ Id = $ _ Get ['id']; // obtain the ID in the URL.

Echo $ ID;

Echo "FDFD ";

?>

Get the id value, and then + FDFD,
