Made With Reflect4 Proxy High Quality Now

For developers who want to create their own solution, here’s a simplified blueprint. Assume you have a pool of residential proxies from a provider like BrightData, Oxylabs, or Smartproxy.

using Reflect4;
using Reflect4.Proxies;
public class HighQualityProxyClient
private readonly ProxyRotator _rotator;
private readonly SessionManager _sessions;
public HighQualityProxyClient(List<ProxyEndpoint> proxyPool)
// Initialize Reflect4 with high-quality settings
    _rotator = new ProxyRotator(proxyPool)
HealthCheckInterval = 5000,      // Check every 5 seconds
        ConcurrencyLimit = 500,          // 500 parallel requests
        StickySessionDuration = 120000,  // 2 minutes same IP
        BlacklistAfterFailures = 3
    ;
_sessions = new SessionManager(_rotator);
public async Task<HttpResponseMessage> SendAuthenticatedRequestAsync(Uri url)
// Get a high-quality, ready-to-use session
    var session = await _sessions.AcquireSessionAsync(
        geoPreference: "US-CA",
        browserFingerprint: FingerprintGenerator.Chrome(120)
    );
// Reflect4 automatically handles headers, TLS, and proxy selection
    return await session.HttpClient.GetAsync(url);

Consider an IUserService interface:

public interface IUserService
Task<User> GetUserAsync(int id);
    void SaveUser(User user);

A high-quality proxy must pass the same tests as the original object. Use this checklist: For developers who want to create their own

// Given: const obj =  a: 1, get b()  return this.a + 1;  ;
// Then the proxy should:
assert(proxy.a === 1);
assert(proxy.b === 2);               // getter uses correct this
assert(Object.keys(proxy).includes('a'));
delete proxy.a;
assert(proxy.a === undefined);
proxy.c = 3;
assert('c' in proxy);

Enforce invariants without cluttering business logic:

public class ValidationInterceptor : IInterceptor
public void Intercept(IInvocation invocation)
foreach (var arg in invocation.Arguments)
if (arg == null) throw new ArgumentNullException();
            Validator.ValidateObject(arg, new ValidationContext(arg), true);
invocation.Proceed();

You can compose interceptors:

var proxy = ProxyBuilder.For<IUserService>()
    .WithInterceptor(new ValidationInterceptor())
    .WithInterceptor(new CachingInterceptor(cache))
    .WithInterceptor(new LoggingRetryInterceptor(logger))
    .Create();

Execution order follows registration (outermost first, then Proceed() chains inward).
