zendriver 0.2.22

//! Demonstrates the browser-context HTTP API (`tab.request()`).
//!
//! `tab.request()` runs `fetch` inside the page, so the request inherits the
//! page's cookies and same-origin CORS rules. Use `.bypass_cors()` to route
//! through Chrome's privileged `Network.loadNetworkResource` path instead
//! (GET only; bypasses CORS).
//!
//! Sequence:
//!   1. Navigate to example.com so that cookies / origin context is
//!      established.
//!   2. Issue a GET to `https://httpbin.org/get` — prints status + truncated
//!      body.
//!   3. Issue a POST with a JSON body to `https://httpbin.org/post` — prints
//!      status + truncated body.
//!   4. Close the browser.
//!
//! No special cargo features required:
//! `cargo run --example browser_request`.
