Managing Origins for Your Property permalink

Origins are your web servers containing the content you want CDN Pro to accelerate. CDN Pro supports more than one origin for each property, along with a number of settings for defining access to your origins.

Adding, Editing, or Removing Origins in a Property permalink

  1. In the left pane, click Edge Configurations, and then select Properties.
  2. From the Properties page, click the ID of the property you want to edit, and then select the version from the Version Number drop-down list.
  3. Click the Edit or Clone button to make changes.
  4. Edit or remove an existing origin or add a new one:
    • If there is an existing origin (similar to the one in the figure below), you can click the Edit link in the Origins field and complete the fields in the following dialog box to edit the origin, or click the Remove link to remove the origin.
    • To add a new origin, click the Add New link, and then complete the fields in the following dialog box. Required fields are denoted by an asterisk (*).

Note: The fields for adding and editing origins are similar.

Upload Certificate Version

Auto DetectThis button appears only when creating a new property. When you click it, CDN Pro tries to resolve the IP address of the hostname you entered for the property. This may or may not be the origin you want to use. Please double-check the results.
Origin NameA name to identify this origin. The origin_pass directive in Edge Logic uses this name to refer to this origin.
ServersEnter a hostname or IP address and the port numbers of a primary origin server.

Click Validate to verify that the server information is correct and reachable.

To add more servers, click the Add new + link. To remove a server, click the Remove link.

If you add more than one server, CDN Pro will distribute origin requests equally among them. To direct more requests to specific servers, enter a percentage value in the Weight field. For example, to have 80% of the origin requests directed to "" and 20% directed to "," assign a weight of 4 to "" and a weight of 1 to ""

Backup ServersBackup origin server that will be used when all primary servers are not accessible. Click Add new + to specify the backup server in the same way as primary servers.
Advanced Settings
Supported ProtocolProtocol(s) that your origin server supports. Choices are:
  • HTTP = use HTTP only.
  • HTTPS = use HTTPS only.
  • Both = use HTTP and HTTPS. (default)
Verify OriginSpecify whether CDN Pro should verify the TLS certificate on the origin servers. Choices are:
  • True = perform backend verification.
  • False = do not perform backend verification. (default)
Host HeaderEnter a Host header value that CDN Pro will use to contact the origin. By default, the value in the client request will be passed through.
Direct ConnectionSpecify how the CDN Pro edge servers should reach the origin servers for uncached content or uncacheable requests. Choices are:
  • No Direct = always go to a parent CDN Pro server. Choose this selection to maximize the cache hit ratio on CDN Pro.
  • Auto = automatically decide whether to go to the origin directly or to a parent CDN Pro server, based on performance and resource availability. (default)
  • Always Direct = the edge servers should always go directly to the origin servers.
Keep-Alive TimeoutThe concept of HTTP keep-alive is to use a single TCP connection to send and receive multiple HTTP requests/responses rather than open a new connection for every single request/response pair. In this field, enter the maximum number of seconds that a connection can remain open before timing out.
AuthenticationEnables authentication for Amazon Web Services (AWS) S3 servers. Choices are:
  • None = no authentication. (default)
  • AWS S3 = enables authentication for AWS S3 servers. If you select this choice, you need to provide additional information to access the S3 bucket:
    • Region = select a region from the drop-down list.
    • Access Key = enter the AWS access key to authenticate with the S3 server.
    • Secret Key = enter the AWS secret key to authenticate with the S3 server.
