Apache rewrite: an example of php pseudo-static html page

The apache rewrite rule has two common tags: [L] and [QSA]. After obtaining pseudo-static data with $ _ GET? The following parameter values must be marked with [QSA.

The differences between [L] and [QSA] are as follows:

1) 'Last | L' (last rule last) immediately stops the rewrite operation and does not apply other rewrite rules.
 
2) 'qsappend | qsa' (append request string append)

This flag forces the rewrite engine to append a request string to an existing replacement string, instead of simply replacing it. If you need to add information to the request string by using the rewrite rule, you can use this flag.
 
Example
 

The code is as follows:	Copy code
For pseudo-static URLs/main/test? Page = 1   RewriteRule ^ main/([a-zA-Z0-9] +) $/index. php? C = main & m = index & a = $1 [L]   $ _ GET ['Page'] cannot be obtained   RewriteRule ^ main/([a-zA-Z0-9] +) $/index. php? C = main & m = index & a = $1 [QSA]   $ _ GET ['Page'] can be obtained

Example

The code is as follows:	Copy code
<IfModule mod_rewrite.c> RewriteEngine on RewriteRule index.html $ index. php RewriteRule index-([1-9] + [0-9] * 2.16.html $ index. php? P = $1 RewriteRule ({a-z}{1, {}-(%0-9}}1 }}.html $ index. php? Action = $1 & id = $2 </IfModule>

The project in the example is test.

Write content to the index. php page of the project

The code is as follows:

Copy code

<? Php If ($ _ GET ['P']) { Echo "p:". $ _ GET ['P']; } If ($ _ GET ['action']) { Echo "action:". $ _ GET ['action']; } If ($ _ GET ['id']) { Echo "id:". $ _ GET ['id']; } ?> Enter Http: // localhost/test/index.html Http: // localhost/test/index-99.html Http: // localhost/test/page-18.html All will go to the http: // localhost/test/index. php page And Http: // localhost/test/index.html the page is not displayed. Http: // localhost/test/index-99.html page displays p: 99 Http: // localhost/test/page-18.html page displays action: pageid: 18

In addition to simple configuration, pseudo-static anti-leech can also be implemented. We only need to configure it briefly.

If you do not want other websites to call images on this website, you can add the following content to the. htaccess or apche configuration file httpd. conf.

The code is as follows:	Copy code
RewriteEngine on # Enable Rewrite module RewriteCond % {HTTP_REFERER }! ^ $ # If you do not directly enter the image address RewriteCond % {HTTP_REFERER }! Img. Your domain name $ [NC] RewriteCond % {HTTP_REFERER }! Google.com [NC] RewriteRule (. *)\. (jpg | jpeg | jpe | gif | bmp | png | wma | mp3 | wav | avi | mp4 | flv | swf) $ http: // your domain/err.jpg [R = 301, L, NC]

Screenshot capture all .jpg or .jpeg ...... Request, jump to http: // your domain name/err.jpg with an error message. Note: the image cannot be in the original domain name or in a folder effectively controlled by the. htaccess file.
