How Tengine Web Server Works

Tengine, like Nginx, operates based on an event-driven, asynchronous, and non-blocking architecture. This means it can handle multiple connections concurrently without creating a new process or thread for each new request, unlike traditional web servers. Instead, it uses a small number of worker processes to handle all requests. This architecture allows Tengine to provide high performance and scalability, even under heavy loads.

When a request comes in, Tengine first determines the type of request (HTTP, HTTPS, etc.) and then processes it accordingly. It uses a modular approach, with different modules handling different aspects of the request, such as parsing HTTP headers, processing PHP scripts, or serving static files.

Architecture of Tengine

The architecture of Tengine is similar to that of Nginx, with some enhancements. It consists of a master process and several worker processes. The master process is responsible for managing the worker processes, while the worker processes handle the actual requests.

Tengine’s architecture also includes several key components, such as event modules, phase handlers, and output filters. Event modules handle events like reading or writing to a network socket. Phase handlers process the different stages of a request, and output filters transform the response before it’s sent to the client.

Key Features and Capabilities of Tengine

Tengine includes all the features of Nginx, along with several additional features. Some of its key features include:

• Dynamic Module Loading: Tengine can dynamically load modules at runtime, allowing you to add or remove functionalities without restarting the server.

• HTTP/2 and SPDY Support: Tengine supports HTTP/2 and SPDY protocols, which can significantly improve the performance of web applications by reducing latency and enabling multiple concurrent exchanges on the same connection.
• Flexible Buffering Options: Tengine provides flexible options for buffering client request bodies. You can specify the number and size of buffers used when reading non-buffered client request bodies, and all the buffers are stored in memory.
• Request Body Postponing: With Tengine, you can control when the server sends the body to the backend. It will send the body either when it receives more than a specified amount of data or when the whole request body has been received. This feature can save the connection and reduce the number of network system calls with the backend.
• Proxy Request Buffering: Tengine allows you to specify whether the request body will be buffered to disk or not. If it’s off, the request body will be stored in memory and sent to the backend after Tengine receives more than a certain amount of data. This can avoid disk IO with large request bodies.
• Customizable ETag Handling: Tengine gives you control over whether the gzip module should clear the “ETag” response header field. This can be useful in certain caching scenarios.

These advanced features make Tengine a powerful, flexible, and secure choice for a web server.
