Data for This Category
Data for this category primarily originates from CDN consoles, DNS resolution records, public network access logs, and node monitoring alerts. Daily produced documents include domain access forms, cache rule configuration tables, refresh and preheating operation records, and fault analysis reports. Unlike cloud network and load balancing configurations, this category focuses on public network content distribution and caching. Data updates occur daily or in real time when configuration changes are made. Most document fields include access domain names, origin server addresses, cache durations, node IPs, and other items. Some fields must match filing information and public network resolution records. The overall structure revolves around full-process configuration for public network content distribution. This page is written based on general logic for form interaction nodes.
Constraints Imposed on Forms and Interactions
The data sources and document structure of this category impose multiple constraints on form interactions. First, the access domain name field must be validated for public domain name format by external business logic, and must connect to an external filing database to verify domain filing status. This prevents submission of access applications that do not meet compliance requirements. Second, cache rule forms must support multi-entry configuration. Each entry must include fields such as matching path and cache duration, and durations must be restricted to valid time units. Bulk rule addition is controlled by external business processes. In addition, the form can connect to node monitoring data from external CDN consoles. It supports quick import of existing refresh and preheating records from external CDN consoles to reduce duplicate data entry. It must also retain an entry point for associating external CDN operation logs to facilitate subsequent fault troubleshooting.
How to Set Configurations
| Configuration Item | Recommended Approach | Rationale for This Approach |
|---|---|---|
Form input node formInput | Test example: Select 3 fields from CDN and edge acceleration configuration fields as required inputs; actual fields are determined based on the task | This node collects user input; interaction status must be checked when required items are missing, to prevent subsequent nodes from receiving incomplete input |
User selection node userSelect | Test example: Set 2 business options, check corresponding branches one by one | This node handles user selection; queries and filtering of CDN and edge acceleration configuration-related records must be implemented by subsequent interfaces or external systems |
| Post-submission field passing | Test example: Prepare 10 CDN and edge acceleration configuration input samples, covering fully filled entries, missing required items, and canceled operations | Compare input and node output to verify whether subsequent nodes receive corresponding fields; result thresholds are determined based on actual tasks |
| External implementation item: Domain verification input box | Must be implemented separately by an external system; use the formInput node to collect input, validate public domain name format via external business logic, and restrict input length to 1–255 characters | Comply with standard length requirements for public network domains, to avoid invalid input |
| External implementation item: Filing status linked selector | Must be implemented separately by an external system; use the userSelect node, with data provided by an external filing database, only display options for filed domain names | Match compliance requirements for CDN access, reduce the probability of subsequent rejection |
| External implementation item: Cache duration configuration item | Must be implemented separately by an external system; use the formInput node to collect input, support a value range of 300 seconds–86400 seconds | Cover common static resource caching needs, while avoiding overly long caching that causes delayed content updates |
Three Common Errors
- Symptom: A "origin server IP format error" prompt appears after submitting the domain access form; Verification action: Check whether the origin server IP entered in the form is a valid public network-accessible IP, confirm that no internal network IP was entered.
- Symptom: Cache rules do not take effect after configuration, and access logs show no matching cache rules; Verification action: Check whether a wildcard was added to the matching path in the form, confirm that only exact paths were configured.
- Symptom: After configuring a third-party CDN endpoint, monitoring data for the corresponding node is not displayed in the form; Verification action: Check whether the external endpoint monitoring interface has been connected to synchronize node status, confirm that only locally cached old data is displayed.
How to Confirm Configuration Completion
- Perform domain filing verification via an external filing database, confirm that the domain name submitted via the form has passed filing verification.
- Check the configuration synchronization status in the external CDN console, confirm that the cache rules submitted via the form have been synchronized to edge nodes.
- Import recent refresh and preheating records, confirm that the form can normally connect to historical operation data from the external CDN console.
- Submit a test configuration, use an external access log query tool to confirm that the matching cache rules have taken effect.
