What is a CDN?

For readers wondering what a CDN is, let me explain a bit

A CDN is a highly distributed server platform optimized for delivering content such as web applications and streaming media.
A CDN directly responds to end-user requests for web content, enabling fast and secure media delivery by distributing its infrastructure across numerous physical network locations.

between the content server and the end user (or client)
it acts as an intermediary server
As the number of end users and requests increases, traffic increases and response delays naturally occur.
With a CDN, you can reduce the burden on the content server caused by those requests!

Getting started with CDN (from applying for an account to completing simple setup)

Create a CDN host

To experience the power of a CDN, there are three steps to set it up as a minimum:

1. Configure the content server (also known as the origin server)

TOP menu screen > CDN host list screen > Click "Add CDN host"
> Click "Origin" in the "Basic Information" section of the new host OXOX.

Finally, click "Add Origin List" from the Origin List list and
change the items in the Origin List editing section as follows.

Example of entry

• Origin List Name: Enter any name
• Protocol: HTTP
• IP Address/FQDN: The IP or FQDN of your origin server
• Port: 80
• Weight: Optional (Leave blank and set to 0 by default)

2. Configuring a CDN host

that we've created a list of content we want to cache on the CDN,
let's change the new host OXOX to our preferred one and add the detailed settings.

TOP menu screen > CDN host list screen
> Click "Settings" in the "Basic Information" section of the new host OXOX.

From the "Basic" tab, change the new host OXOX to any hostname you like, and the name displayed in the CDN host list will change.
From the "Origin" tab, add the settings as shown below.

Example of entry

• Origin server type: Customer origin
• Fetch Protocol: HTTP
• Select origin list: The name of the origin list created in step 1
• Host header: The IP or FQDN you entered in the origin list in step 1

To apply the settings, return to the CDN host list and click the checkbox to the left of the hostname. Then
click the "Apply CDN Settings" button in the upper right corner of the same screen.
The settings will then be completed in about 1 minute.

3. DNS Server Settings

TOP menu screen > CDN host list screen
> Click "Settings" from the "Basic Information" item, which now has a more user-friendly name.

From the "FQDN" tab, note down the FQDN displayed in the "CNAME Information" field.
Enter this into the CNAME setting on your DNS server, and the simple setup is complete.

Check it from your browser

Connect to your content server (blog, personal website, etc.) from your web browser and
open the developer mode provided by your browser. In Chrome, you can do this by pressing the F12 key.
Clicking on the image file displayed in the "Name" column of the "Network" menu
will output the header information (labeled "Headers") on the right.
If it is cached on J-Stream's CDN, the "via" field in the "Response Headers" column JSTCDNwill display

I apologize to users of other browsers, as I am a Chrome user, but
I believe other browsers also have some kind of developer mode, so please check them out yourselves.
