Proxy Rotation Strategies

Why Rotation Matters

Websites detect and block IPs that make too many requests. Rotation distributes your traffic across multiple IPs, avoiding detection.

Rotation Strategies

1. Random Rotation

The simplest approach: pick a random proxy for each request.

Pros:

Cons:

When to use:

2. Sticky Sessions

Keep the same proxy for a series of related requests.

Implementation:

# Pseudo-code

session_proxies = {}

def get_proxy(session_id):

if session_id not in session_proxies:

session_proxies[session_id] = random.choice(proxy_pool)

return session_proxies[session_id]

When to use:

3. Round-Robin Rotation

Cycle through proxies in order, ensuring even distribution.

Pros:

Cons:

When to use:

4. Weighted Rotation

Prioritize better-performing proxies.

Implementation:

# Pseudo-code

weights = calculate_weights(proxy_metrics)

selected = random.choices(proxy_pool, weights=weights)[0]

Factors for weighting:

5. Backoff Rotation

Rotate when a proxy shows signs of blocking.

Triggers:

Implementation:

# Pseudo-code

def on_failure(proxy):

proxy.failures += 1

proxy.cooldown_until = now() + backoff_time(proxy.failures)

return get_fresh_proxy()
