Struct HttpPushNotificationSender 

pub struct HttpPushNotificationSender { /* private fields */ }

Available on crate features server and a2a-v1 only.

HTTP-based push notification sender with retry and SSRF validation.

Uses reqwest::Client to POST JSON payloads to webhook URLs. Retries up to 3 times with exponential backoff (1s, 2s, 4s) on failure. Validates webhook URLs to reject private IP ranges and localhost (SSRF prevention).
