Session Lock vs IP Rotation: When to Use Each

Session Lock vs IP Rotation: When to Use Each

Two fundamental proxy strategies exist: keeping the same IP (session lock) or changing IPs frequently (rotation). Most proxy services force you to choose one. HydraSkill lets you use both — and picks the right one automatically.

Session Lock: Same IP, Entire Task

Use when: Your task requires continuity with the target website.

Real-World Scenarios

E-commerce checkout flow:

Browse → Add to cart → Enter shipping → Payment

If your IP changes between “add to cart” and “payment,” the cart is empty. Session Lock keeps the same IP throughout.

Multi-page scraping with pagination:

Page 1 → Page 2 → ... → Page 50

Some sites track session by IP. Changing IP mid-pagination can trigger anti-bot detection or reset your position.

Account management:

Login → Navigate → Perform actions → Logout

Accounts get flagged when the IP changes during an active session.

Code

proxy = client.get_proxy(
    target="amazon.com",
    session_lock=True,
    session_ttl=3600  # keep for 1 hour
)

# All requests use the same IP
for page in pages:
    requests.get(page, proxies=proxy.to_dict())

proxy.release()

IP Rotation: New IP, Every Request

Use when: You need to appear as many different users.

Real-World Scenarios

Price monitoring across regions:

Check price from US IP → Check from UK IP → Check from JP IP

Each request should come from a different location.

Search result scraping:

Query 1 → Query 2 → ... → Query 1000

Search engines rate-limit per IP. Rotating gives you more queries before hitting limits.

Ad verification:

View ad from IP A → View from IP B → View from IP C

You need to see what different users see.

Code

# No session_lock = new IP each time
for query in queries:
    proxy = client.get_proxy(target="google.com", country="US")
    requests.get(f"https://google.com/search?q={query}", proxies=proxy.to_dict())
    proxy.release()  # return IP to pool immediately

Decision Matrix

Scenario	Strategy	Why
Checkout flows	Session Lock	Cart requires IP continuity
Pagination	Session Lock	Avoid detection mid-crawl
Account actions	Session Lock	Prevent security flags
Price comparison	Rotation	Need multiple geolocations
Bulk search queries	Rotation	Avoid per-IP rate limits
Ad verification	Rotation	Simulate different users
API access	Either	Depends on rate limits

HydraSkill’s Approach

With Context-Aware Routing, you often don’t need to decide manually:

# HydraSkill analyzes the target and picks the right strategy
proxy = client.get_proxy(target="amazon.com")
# → Automatically uses session lock for e-commerce

proxy = client.get_proxy(target="google.com/search")
# → Automatically rotates for search

Combining Both

Some tasks need both strategies in sequence:

# Phase 1: Research (rotation)
for product_url in discover_products():
    proxy = client.get_proxy(target="amazon.com")
    data = scrape(product_url, proxy)
    proxy.release()

# Phase 2: Purchase (session lock)
proxy = client.get_proxy(target="amazon.com", session_lock=True)
add_to_cart(proxy)
checkout(proxy)
proxy.release()

Key Takeaway

Don’t default to one strategy. Match your proxy behavior to your task requirements. HydraSkill makes this easy by handling the decision automatically — or letting you override when you know better.
