CDN77 Documentation

Customizable URL Redirects allow the definition of rules to map source URLs to destination URLs based on exact matches or regular expressions. Redirections are processed at the CDN edge servers, ensuring a seamless transition for the user without requiring manual intervention. This feature is primarily used to maintain link integrity during website reorganization, optimize navigation, and ensure content availability.

IP access control allows you to whitelist or blacklist specific sets of IP addresses to protect your content from unwanted access.

Custom parameter-based path handling is an advanced CDN feature that allows you to customize content paths based on specific parameters included in the URL. This is typically used for dynamic content generation (such as serving different language versions of a page), A/B testing, personalization, and resource optimization. When a request contains the specified parameters, the CDN processes the request according to pre-configured rules to return the appropriate path to the end user.

CDN77 Object Storage is an S3-compatible service designed for storing large amounts of unstructured data. It organizes data into objects (containing data and metadata) rather than traditional file hierarchies. Because it is directly integrated into the CDN77 CDN infrastructure, traffic and requests between the storage and the CDN are free of charge. All clusters are compatible with S3 API operations and the AWS SDK.

Response manipulation allows for the customization and modification of content (such as response bodies and headers) sent from the origin server before it is delivered to the end user. The CDN edge servers intercept the origin response and apply predefined rules or scripts in real-time to ensure only safe, compliant, and necessary information reaches the client.

CDN77 Real-Time Logs provide near-immediate visibility into interactions between client requests and server responses for specific CDN Resources. Logs are generated and uploaded in batches every 30 seconds. They are used to analyze statistics, detect anomalies, and resolve issues quickly. Data is accessible via the CDN77 Client Panel and a dedicated S3 bucket as gzip files for deeper analysis.

The Custom HTML Pages for HTTP Error Responses feature allows you to define and serve personalized, branded HTML pages when specific HTTP error codes are triggered. This is used to improve user engagement and retention by replacing generic browser error pages with informative messages and navigation options to guide users back to functional parts of the site.

Secure tokens protect content by generating a unique hash that prevents unauthorized access to a URL or file. When enabled in the Access protection section of a CDN Resource, a secret key is provided to be used in the hash generation process. Secure tokens allow for expiration timestamps and optional IP address locking to ensure content is only accessible to specific users for a predefined period.

Customizable Cache Keys allow you to define the unique identifier used to store and retrieve cached content. Instead of a default key, you can specify which request attributes—such as URL parameters, HTTP headers, cookies, or specific URL structure segments—construct the cache key. This is primarily used to cache different variations of the same content (e.g., language-specific versions) as independent cache entries, ensuring that users receive content tailored to their specific request attributes.

CDN resources operate on an 'Origin pull' mechanism. When a visitor requests a file, the CDN checks its cache: if the file is present, the edge server delivers it directly; if the file is not found, the CDN pulls the file from the Origin server, caches it, and then delivers it to the visitor.

For Monthly and Growth Plan clients, CDN Credit covers services not included in the base monthly traffic payment, such as storage, logs, and overages. Detailed deduction information is available at the bottom of the Billing Overview page. Users can top up their credit via the Client Panel.
