Sticky vs Rotating Proxies: Discover When You Should Use Each
Linda Johnson
Rotating your proxy IP can be a very helpful function during your scraping or parsing missions on the Web. However, in some select cases, you may need to use proxies with unchanging IP sessions instead of a new IP on each connection. This is exactly when you will require the functionality of sticky proxies.
In this article we will take a closer look at cases when you may need to consider deploying sticky vs rotating proxies. You will learn about the main difference between the two types of proxies and the technology behind them. We will close by the information related to PrivateProxy’s standing on the subject and our best offers to our clients.
Defining Sticky Session
A sticky port proxy (or simply a sticky proxy) is a server that keeps the same IP for a duration of time set for this session, i.e. several seconds or minutes. The IP changes when this interval lapses. Such a process is referred to as a sticky session.
Some people confuse proxies with sticky sessions and static proxies. In the case of static proxies – you can have a valid IP for the duration of several months. This is possible because ISP and dedicated datacenter proxies can secure this address for your missions this long. With residential proxies you need actual physical users to be online to use their IPs. This sets the limit for the sticky session duration. So, with some proxy providers your IP rotation will be compulsory after a certain time, even if they try to guarantee you long proxy sessions.
Defining Rotating Session
A rotating proxy is a server that changes its IP for each session (or request). This helps the users hide the fact that scraping is performed by a single device. You can have thousands of requests route to the same website over the period of your operation, and each of the requests will be forwarded from a different IP selected from the pool.
This kind of scenario ensures random intervals of IP rotations and is useful especially for overriding anti-bot systems of search engines and e-commerce sites for collecting valuable data related to marketing. With constantly changing IPs, your proxy has less chances of being detected by the anti-scraping systems.

When you get “The proxy server isn’t responding” error on your system, do not panic blaming your hardware for it. Normally, all of your devices – the router, modem, etc. – are fully functional and the root of the problems with proxy server lies in the malware that you had accidentally downloaded.
