Overview
After a domain name is added for acceleration, you can configure the domain name based on service requirements. Customized configuration items include basic settings, origin pull, HTTPS, cache, access control, and advanced settings.
OBS Authorization
Item |
Description |
---|---|
If you configure a Huawei Cloud OBS private bucket as the origin server, you must enable OBS authorization so that CDN can pull content from your private bucket. |
Basic Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
If the IP address or domain name of the origin server changes, origin server information is incorrect, or a standby origin server is needed, modify the origin server settings. |
|
If the domain name you want CDN to pull content is not your acceleration domain name, set a host header. CDN regards an acceleration domain name as the host by default. |
|
If the services of your domain name change and its service type cannot meet your requirements, you can change the service type on the CDN console. |
|
If the region where your users are located changes, you can change the service area of your acceleration domain name to better match your services. |
|
To allow users to access CDN PoPs using IPv6, enable IPv6 on the CDN console. |
Origin Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
You can configure the request protocol used by CDN for origin pull. |
|
If your origin server IP address is bound to multiple domains and CDN visits the origin server using HTTPS, you can set the Server Name Indication (SNI) to specify the domain to be visited by CDN. |
|
If the URLs of origin pull requests do not match the origin server URLs, you can rewrite the request URLs to improve the origin pull hit ratio. |
|
You can configure advanced origins to allow CDN to pull content from different origin servers based on different resource types or paths. |
|
If you need to improve the distribution efficiency of large files, you can enable range requests. |
|
Assume that 302/301 redirect is performed for your origin server address. If you do not want CDN to directly send a 302/301 redirect address to users but to instead cache the requested content and then forward the content to users, you can enable redirect from origin. |
|
If your resources on the origin server remain unchanged and you do not want CDN to pull the resources after the cache expires, you can enable ETag verification. |
|
You can rewrite a header in an origin pull request on the CDN console. |
|
You can adjust the origin response timeout based on the features and service scenarios of your origin server. |
HTTPS Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Function |
Description |
---|---|
You can add a certificate for HTTPS acceleration. |
|
Describes the combination and upload sequence of certificates issued by different authorities |
|
You can convert certificates in other formats to the PEM format that CDN supports. |
|
You can enable or disable TLS versions as required. |
|
You can force redirect to HTTP or HTTPS. |
|
You can configure HSTS to force clients (such as browsers) to use HTTPS to access your server, improving access security. |
|
Describes the background and advantages of HTTP/2. |
|
If you enable this function, CDN will cache the status of online certificates in advance and return the status to browsers. Browsers do not need to query the status from CAs, accelerating the verification. |
|
You can configure the QUIC protocol to improve transmission security, reduce transmission and connection latency, and prevent network congestion. |
Cache Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
|
|
You can cache error status codes returned by the origin server to CDN PoPs, so CDN can return the error codes to users when they request resources. You can also set the status code cache TTL to reduce origin pull and pressure. |
Access Control
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
Configure this item when you need to identify and filter visitors to restrict access. |
|
Configure this item when you need to use IP address filtering to restrict access. |
|
Configure this item when you need to use User-Agent filtering to restrict access. |
|
Configure this item when you need to protect your website resources from being downloaded by malicious users. |
|
Configure this item to allow CDN to forward user requests to a specific server for authentication, to prevent malicious resource download. |
Advanced Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
You can customize values of HTTP response headers for your website. |
|
You can customize error pages returned to user clients. |
|
You can compress static content on your websites by reducing file size. This speeds up file transfer and saves you a lot of bandwidth. |
|
If you have enabled whole site acceleration in scenarios such as on-screen commenting, collaborative session, market data broadcast, sports live update, online education, and IoT, you can configure WebSocket to implement long-term bidirectional data transmission. |
|
You can limit the user request rate within a specific range to reduce costs and the risk of burst bandwidth. |
|
You can set a traffic or bandwidth cap for a domain name. When the usage reaches the cap, CDN acceleration will be disabled for the domain name, reduce high bills caused by traffic theft or attacks. |
Video Settings
Ensure that the domain name is in the Enabled or Configuring state and is not locked or banned by CDN before configuring the settings.
Item |
Description |
---|---|
Configure this item to allow users to seek to a certain position in a video without affecting the playback effect. |
