In the daily work, two dogs is actually a hidden big touch, a brilliant sketch, many read small partners cry for sharing. In order to let more young fans see his work, Erdogzi developed a website that provides copyrighted sketches for download.

Two dog son’s small website, as long as the registered user can unlimited speed download sketch. This is originally a good thing, but with the increase in traffic, bandwidth cost became two dogs unbearable weight. Therefore, some friends suggested to make a VIP service, let THE VIP download at full speed, free users a little speed limit. Two dogs think this is a very good way, so open Baidu to find a specific way of operation.

If you need to limit the speed at which others can download from your site, use the Rewrite rule.

What is the Rewrite rule?

Rewrite is a server rewriting technique whose main function is to redirect urls. Its regular expressions are based on Perl. It can be both server-level (httpd.conf) and directory-level (.htaccess).

If you want to use the Rewrite module, you must first install or load it. There are two ways to do this: install the Rewrite module directly when you compile Apache; The other is to install Apache in DSO mode when you compile Apache and then use the source code and APXS to install the Rewrite module.

The above two methods of implementation, two dogs see confused, feel separate to each word can understand, connect and as if the book. Helpless two dog son try to ask for help omnipotent cloud customer service – Vivian little sister.

“Just plug into the Rewrite CDN and you can do it directly from the console.” Vivian little sister calm answer.

Boy! Worthy of being two dogs favorite and clap cloud, come to see the specific use of it.

Rewrite use case

Rewrite () : how to configure the speed limit? Vivian little sister told two dogs, general and programming two modes can be achieved, and step by step to personally demonstrate how to operate.

General mode:

Programming mode:

This rule indicates that when the URL matches the domain name, the rate limiting starts 1 KB after the file is loaded. The rate limiting value is 60 KB.

After the completion of the two dogs immediately tested, the Settings will take effect, immediately completed the speed limit.

Weiwei also told erguzi, in addition to the domain name speed limit, can also be specified type of file download speed limit, such as: specified zip file download speed limit.

Once this setting is complete, when the accessed URL matches the domain name and files with the suffix, the rate limiting starts.
