Fundamentals
Proxy Basics
Learn the core proxy types, protocols, and decisions before you configure a service.
The practical proxy knowledge base
Understand proxies. Make better choices.
Independent-minded, technically accurate guides to proxy types, protocols, authentication, configuration, responsible data collection, and troubleshooting.
Make a requirements-first choice
Choose a proxy from the workflow, not the label
Compare exclusive or shared access, fixed or rotating IP behavior, protocol support, location, and authentication before you order. The checklist turns those terms into a controlled test.
START WITH THE RIGHT PATH
