What Is Middleware?
Middleware is software that sits between a request and the response in a web app. It handles tasks such as security checks, logging, authentication and routing.
Common examples of middleware
- Authentication (checking users are logged in)
- Error handling and logging
- Rate limiting for APIs
- Compression and performance optimisation
- Redirects and URL rewrites
Why SMEs rely on middleware
Middleware keeps bespoke systems clean, fast and secure — especially important for SMEs across London, Hertfordshire and Essex who depend on internal platforms.
