Domains

Domain names are used for a variety of reasons, including application specific naming, addressing and establishing the following in various networking contexts. Hostnames and source addresses can be easily identified with URLs. When you use Asians Cloud CDN service, you associate your domain names with your origin so that you can appropriately route requests to your website and ensure that others cannot serve requests to that domain. For instance, you may type {www.example.com}, {blog.example.com}, or even {*.example.com} as a wildcard. At any time, you can add, change, or remove domains from your service.

Source address

Both the source and destination addresses are included in IP packets. When a communication is established, the source transmits an IP packet to the destination. The destination sends a response packet to the IP packet's source address. If the source address is incorrect, the destination will not be able to respond correctly.

Origin server

The primary function of an origin server is for processing and responding to incoming internet requests from clients. An origin server is essentially a machine that runs one or more programs that listen for and handle incoming internet traffic. An origin server can handle all of the kinds of web requests as long as the traffic does not exceed the server's capacity and latency is not a major concern. Website owner is responsible for maintaining and updating the origin server. While CDNs handle a large percentage of content distribution, they don't take over all of the work from the origin servers. The amount of work that can be offloaded is determined by the CDN's capabilities as well as the particular features of your website. CDN servers can cache static resources such as CSS files, pictures, static HTML, and Javascript files in general. And they account for about half of all bandwidth consumption. Furthermore, modern CDNs may cache dynamic material such as WordPress HTML files generated on the fly, resulting in bandwidth savings of up to 80% in some circumstances.

Asians Cloud CDN do not recommend using wildcard domain {*.example.com} as primary domain name.
