Function doForwardProxyRequest

cmd/cache-proxy/proxy_test.go:112–123

doForwardProxyRequest sends a request through the proxy in forward-proxy form (absolute URI in the request line). httptest's serve path preserves the URL.Host and URL.Scheme when we construct the request this way.

(proxy *CacheProxy, method, absoluteURL string, headers http.Header)

// newTestProxy wires a CacheProxy with no peers and a tempdir-backed store.

	proxy := NewCacheProxy(newTestCache(t), nil, nil)

}

// newTestServer returns an httptest origin plus a proxy that rewrites inbound
// forward-proxy-style requests to target that origin. DuckDB sends absolute-form
// URIs (scheme + host + path); we give the test the origin's URL so the proxy's
// fetchOrigin hits httptest.Server directly.
