Struct UrlTracker 

pub struct UrlTracker {
    pub counts: Arc<DashMap<String, usize>>,
}

Thread-safe hit counter for presigned URLs.

Tracks how many times each presigned URL has been used so that a configurable maximum can be enforced. Regular (re-signed) requests are not tracked — the aws-cli issues parallel range-GET sub-requests for the same object, which would exhaust a small limit instantly.

Internally backed by a [DashMap] so that concurrent access from multiple Pingora worker threads never requires a global lock.

Fields

counts: Arc<DashMap<String, usize>>

Per-URL hit counters.

Implementations

impl UrlTracker

pub fn new() -> Self

Create a new, empty tracker.

pub fn get(&self, url: &str) -> Option<usize>

Return the current hit count for url, or None if it has never been tracked.

pub fn get_all(&self) -> Vec<(String, usize)>

Return a snapshot of all tracked URLs and their counts.
