Advanced Proxy Integration Strategies

Proxy Architecture Patterns

1. Multi-Layer Proxy Implementation

class MultiLayerProxy:
    def __init__(self):
        self.residential_pool = ProxyPool(‘residential‘)
        self.datacenter_pool = ProxyPool(‘datacenter‘)
        self.mobile_pool = ProxyPool(‘mobile‘)

    def get_optimal_proxy(self, request_type):
        success_rates = {
            ‘residential‘: self.residential_pool.success_rate,
            ‘datacenter‘: self.datacenter_pool.success_rate,
            ‘mobile‘: self.mobile_pool.success_rate
        }
        return max(success_rates.items(), key=lambda x: x[1])[0]

2. Advanced Session Management

class EnhancedSession:
    def __init__(self):
        self.session_pool = []
        self.proxy_mapping = {}
        self.success_metrics = {}

    def create_session(self, proxy):
        scraper = cloudscraper.create_scraper(
            browser={
                ‘custom_chrome‘: True,
                ‘platform‘: self._get_random_platform(),
                ‘mobile‘: random.choice([True, False])
            }
        )
        return self._configure_session(scraper, proxy)
