Struct ServerCacheOptions 

pub struct ServerCacheOptions {
    pub default_ttl: Option<Duration>,
    pub max_ttl: Option<Duration>,
    pub min_ttl: Option<Duration>,
    pub cache_status_headers: bool,
    pub max_body_size: usize,
    pub cache_by_default: bool,
    pub respect_vary: bool,
    pub respect_authorization: bool,
}

Configuration options for server-side caching.

Fields

default_ttl: Option<Duration>

Default TTL when response has no Cache-Control header.

max_ttl: Option<Duration>

Maximum TTL, even if response specifies longer.

min_ttl: Option<Duration>

Minimum TTL, even if response specifies shorter.

cache_status_headers: bool

Whether to add X-Cache headers (HIT/MISS).

max_body_size: usize

Maximum response body size to cache (in bytes).

cache_by_default: bool

Whether to cache responses without explicit Cache-Control.

respect_vary: bool

Whether to respect Vary header for content negotiation.

When true (default), cached responses are only served if the request’s headers match those specified in the response’s Vary header. This is enforced via http-cache-semantics.

respect_authorization: bool

Whether to respect Authorization headers per RFC 9111 §3.5.

When true (default), requests with Authorization headers are not cached unless the response explicitly permits it via public, s-maxage, or must-revalidate directives.

This prevents accidental caching of authenticated responses that could leak user-specific data to other users.
