Continue urlrewrite. Today we bring some more things.

First of all, turn an article, source: http://www.zuoyefeng.com/show.aspx? Id = 79 & cid = 70

URL rewrite. My translation is URL rewriting or URL redefinition. In ASP + IIS web development mode, can be implemented such as the http://xxxxxx.cn/news.asp? Id = 220 is in the form of a http://xxxxxx.cn/220.html. For example, the actual website of a news article is http://xxxxxx.cn/news.asp? Id = 220. After URL rewriting, we can directly enter the URL of the http://xxxxxx.cn/220.html to access the news.

For IIS servers, to achieve this feature, you need to download the lite version (free) free version of the software from the http://www.helicontech.com/download/ website, the software installed on the server, in its installation directory, find the configuration file httpd. INI, open it in notepad, and enter the corresponding rules. Then, add this component to ISAPI on the corresponding site. OK. The configuration is complete and the function takes effect.

2. For details about how to write url_rewrite rules, refer:

When I need? When id = 234 is mapped to news/234.html, you only need to set:

Rewriterule/news/(\ D +) \. html/news \. asp \? Id = $1 [N, I]

In this way, requests such as/news/234.html are mapped to/news. asp? Id = 234
When there is a request for/news/234.html: the Web server will forward the actual request to/news. asp? Id = 234

For a simple application:

Rewriterule/news/(\ D +) \. html/news \. php \? Id = $1 [N, I]

So we map the http://www.xxxxxx.com/news/234.html to the http://www.xxxxxx.com/news/news.php? Id = 234

A more general expression that can map parameters of all dynamic pages is:
Put http://www.xxxxxx.cn/foo.php? A = A & B = B & C = C
Represented as http://www.xxxxxx.cn/foo.php/a/A/ B/B /c/C

Rewriterule (.*? \. Php )(\? [^/] *)? /([^/] *)/([^/] *) (. + ?)? $1 (? 2 $2 &:\?) $3 = $4? 5 $5: [N, I]

3. Benefits of using URL rewriting:

First, it helps increase website security because it hides server technologies such as asp php jsp and presents them to customers in the most primitive HTML file format.

Second, when the platform is migrated, there will be no websites on each page. For example, add news. asp? Id = 123 transfer news. php? Id = 123, which transfers the ASP platform to PhP. If this URL is used for rewriting, the URL of this page is news/123.html.

In other aspects, it facilitates URL reference and facilitates enumeration of search engines.
