2. Understanding HTTPS Proxies

2.1 Proxy Protocols Deep Dive

Modern proxy implementations support multiple protocols:

const PROXY_PROTOCOLS = {
    HTTP: {
        port: 80,
        encryption: false,
        performance: ‘High‘
    },
    HTTPS: {
        port: 443,
        encryption: true,
        performance: ‘Medium‘
    },
    SOCKS4: {
        port: 1080,
        encryption: false,
        performance: ‘High‘
    },
    SOCKS5: {
        port: 1080,
        encryption: true,
        performance: ‘Medium‘
    }
};

2.2 Protocol Performance Comparison

Protocol	Latency (ms)	Throughput (MB/s)	Security Level
HTTP	20-30	80-100	Low
HTTPS	30-40	60-80	High

            this.pool.set(proxyUrl, []);
        }

        const connections = this.pool.get(proxyUrl);

        if (connections.length < this.maxConnections) {
            const connection = await this.createConnection(proxyUrl);
            connections.push(connection);
            return connection;
        }

            [‘leastConnections‘, this.leastConnections.bind(this)],
            [‘weighted‘, this.weighted.bind(this)]
        ]);

        this.currentStrategy = strategies[0];
        this.proxyStats = new Map();
    }

    async selectProxy(proxyList) {
        return this.strategies.get(this.currentStrategy)(proxyList);
