Rotating vs Sticky Proxies — Which Should You Use?

Proxy rotation strategy is one of the most important configuration decisions in any proxy workflow. The choice between rotating (new IP per request) and sticky (same IP for a session) directly affects success rates, detection risk, and workflow design.

How Rotating Proxies Work

Rotating proxies assign a new IP address for every request. When you send 1,000 requests, each one exits through a different IP. The target site sees 1,000 different visitors rather than 1,000 requests from the same address. This is the default behavior on most proxy infrastructure, including Hex Proxies.

Rotation eliminates the primary trigger for rate limiting: repeated requests from a single IP. Search engines, e-commerce sites, and social media platforms all track request frequency per IP. By rotating on every request, you stay below detection thresholds even at high volume.

How Sticky Proxies Work

Sticky proxies maintain the same IP address for a defined session duration, typically 1 to 30 minutes. You specify a session identifier in your proxy configuration, and all requests with that session ID route through the same IP. When the session expires, the next request gets a new IP.

Sticky sessions are essential for workflows that require state. If you need to log into a website, navigate multiple pages, add items to a cart, and check out, those requests must come from the same IP. A rotating proxy would assign different IPs to each step, which would break the session and trigger security alerts on the target platform.

When to Use Rotating Proxies

Rotating is the right choice for stateless, high-volume data collection.

• SERP tracking: Each search query should come from a different IP to avoid Google's rate limits. Rotating proxies with city-level targeting show you localized results across different geographies.

• Price monitoring: Checking product prices across hundreds of e-commerce listings benefits from IP diversity. Each product page request appears as a unique visitor.

• Ad verification: Verifying ad placement across different locations requires unique IPs per check. Rotating proxies ensure each verification request is independent.

• Content scraping: Collecting article text, product descriptions, or review data at scale works best with rotation to distribute requests across the IP pool.

When to Use Sticky Proxies

Sticky sessions are essential for stateful interactions.

• Account management: Logging into social media accounts, e-commerce seller dashboards, or banking portals requires consistent IPs throughout the session. Platforms flag sessions where the IP changes mid-interaction.

• Shopping and checkout: Multi-step purchase flows track the user's IP from cart to payment. Rotating mid-checkout triggers fraud detection.

• Form submission: Multi-page forms that store state between steps require sticky sessions to maintain continuity.

• Platform browsing: Browsing deeply into a site (paginating search results, filtering products) often requires session consistency to avoid CAPTCHAs.

Hex Proxies: Both Modes, One Infrastructure

Hex Proxies supports both rotating and sticky sessions across all proxy types. Rotating is the default behavior. To enable sticky sessions, append a session identifier to your proxy credentials. Sessions persist for up to 30 minutes on residential proxies and indefinitely on ISP proxies (dedicated IPs).

ISP proxies are particularly effective for sticky use cases because they provide a dedicated IP that remains consistent as long as your plan is active. Unlike residential sticky sessions that expire, an ISP proxy gives you a permanent stable IP with residential trust. This makes ISP proxies the optimal choice for long-running account management and checkout workflows.

Frequently Asked Questions

Can I switch between rotating and sticky mid-workflow?

Yes. On Hex Proxies, rotation behavior is controlled per request through session parameters. You can use rotating proxies for initial scraping and switch to sticky sessions for authenticated interactions, all on the same proxy plan.

Do sticky sessions cost more?

On Hex Proxies, there is no additional cost for sticky sessions. The same residential bandwidth rates apply whether you rotate per request or maintain a session. ISP proxies provide permanent sticky IPs with unlimited bandwidth included.

How long can sticky sessions last?

On Hex Proxies, residential sticky sessions last up to 30 minutes. ISP proxies provide dedicated IPs that remain assigned to your account indefinitely, giving you permanent sticky sessions without expiration.
