Nuster vs Squid: What are the differences?

## Introduction
Nuster and Squid are both popular web caching servers used to improve the performance of web applications by caching frequently accessed web content. However, they have key differences that set them apart from each other.

## 1. **Architecture**: 
Nuster is designed to be event-driven and runs as a single process, utilizing asynchronous I/O for high performance. Squid, on the other hand, is a multi-threaded application that can handle multiple client requests concurrently.

## 2. **Configuration**: 
Nuster has a simpler configuration syntax compared to Squid, making it easier to set up and manage. Squid, on the other hand, offers more granular control over caching policies and has a wide range of configuration options.

## 3. **SSL/TLS Termination**: 
Nuster can terminate SSL/TLS connections directly, which can offload the SSL/TLS processing from backend servers. Squid requires additional tools or configurations to handle SSL/TLS termination.

## 4. **Support for HTTP/2**: 
Nuster natively supports HTTP/2 protocol, providing faster and more efficient communication between clients and servers. Squid may require additional configurations or plugins to support HTTP/2.

## 5. **Dynamic Content Caching**:
Nuster is better suited for caching dynamic content due to its event-driven architecture, allowing it to efficiently cache and serve dynamic web pages. Squid, while capable of caching dynamic content, may not be as optimized for this purpose.

## 6. **Ease of Monitoring**:
Nuster provides built-in monitoring and statistics capabilities, making it easier to track cache performance and diagnose issues. Squid may require external monitoring tools or configurations for detailed cache monitoring.

In Summary, Nuster and Squid differ in key aspects such as architecture, configuration, SSL/TLS termination, support for HTTP/2, dynamic content caching, and monitoring capabilities.
