In scenarios such as web crawlers, cross-border business operations, ad verification, and API calls that rely on proxy services, Novproxy users often encounter a core decision-making dilemma: Should they opt for frequent IP switching to ensure anonymity in round-robin conversations, or should they prioritize maintaining a fixed IP to ensure session continuity in sticky sessions? This article systematically examines the core differences between the two session modes of Novproxy and provides clear selection recommendations based on actual business scenarios.
IP rotation refers to the process of randomly changing your IP address to another IP address.
The sticky session will retain the same IP address for a specific period of time: 1 minute, 10 minutes, 30 minutes, and so on. This is the sticky session. After setting the time you desire, if you exceed that period, you will obtain a new IP address.
| Dimension | Rotation conversation | Sticky conversation |
| IP replacement mechanism | Automatically assign a new IP for each request | Maintain the IP until timeout / expiration |
| Anonymity | ★★★★★ (High-frequency switching to avoid tracking) | ★★★★ (Fixed-duration IP is prone to being flagged) |
| Session continuity | ★ (Stateless, unable to maintain login status) | ★★★★★ (Supports long-term sessions) |
| Key parameters | No additional configuration required | Configuration required for duration |
| Timeout rules | Instant switching | 1-120 minutes |


- Large-scale data collection: When a crawler fetches multiple pages, changing the IP for each request can avoid frequency restrictions, and combining with random access intervals can reduce the risk of being blocked.
- Ad verification / Competitor monitoring: High anonymity ensures that the proxy identity is not identified by the target website, guaranteeing the authenticity of the data.
- High-frequency short-term tasks: such as real-time monitoring of flash sales, real-time stock price capture, without maintaining a session and avoiding IP blocking.
The choice between sticky sessions and rotating sessions in Novproxy is essentially a precise match of “business requirements and proxy characteristics” – neither has absolute superiority or inferiority; only differences in scenario adaptation exist. It is recommended that users, in actual applications, first clearly define the core business requirements, and then implement them by considering details such as session timeout rules and parameter configuration requirements.
