Accelerate dynamic APIs and apps

Application Accelerator is an Applications module for accelerating web applications and APIs through protocol optimizations and advanced cache rules. It enables protocol optimization for dynamic content, Advanced Cache Key processing with query strings and cookies, POST and OPTIONS request caching, and short TTL support. The module reduces latency and improves throughput for data-intensive applications on Azion Web Platform.

Advanced Cache Key lets you control how content is segmented in cache beyond the URL path. You can configure cache variation rules based on query strings, cookies, and headers—enabling fine-grained control over which parameters differentiate cached objects. This supports up to 64 custom cache keys per edge application.

Yes. You can configure cache variation by specific query string fields using four modes: Whitelist (only listed fields considered), Blocklist (ignores specified fields), All fields (considers all variations), and Query String Sort (order becomes irrelevant). This lets you control exactly which parameters affect cache segmentation.

Yes. You can configure cache variation by specific cookie names, which is useful for session-based or personalized content. Modes include: URL-based only, Whitelist (allowed cookies), Blocklist (exceptions), and All cookies. This enables content segmentation by user profiles, browsing sessions, access regions, and targeting needs.

Create cache settings in the Applications module, then activate them with Rules Engine rules. You can use request or response phase logic to decide when a cache policy should apply. This allows granular control over caching behavior based on URL patterns, headers, cookies, or other request attributes.

Yes. With Application Accelerator enabled, you can customize short cache TTL values, including immediate expiration. This is ideal for rapidly changing content and real-time applications that require near-instant cache invalidation.

Yes. Application Accelerator enables caching for POST and OPTIONS requests, extending beyond the default GET and HEAD methods. When enabled, the request body becomes part of the cache key, so different payloads are cached separately. This is optimized for frequently accessed or data-intensive API endpoints.

Traditional CDN caching typically supports only GET and HEAD requests with limited cache key customization. Application Accelerator provides protocol optimization for dynamic content, Advanced Cache Key with query string and cookie support, POST/OPTIONS caching, and short TTLs, all on a distributed architecture without cold starts. This enables caching strategies not possible with standard CDN configurations.

Default cache TTL limits include a configurable minimum and maximum range. You can choose values based on your content requirements, with short TTL support available when Application Accelerator is enabled.

Application Accelerator is a premium module with usage-based pricing. Advanced cache features require the module to be active, and data transfer may generate additional costs depending on your configuration. Contact Azion support for specific pricing details based on your plan and expected usage.
