Nginx FastCGI caching dramatically reduces PHP processing load by storing rendered responses on disk and serving them directly to subsequent visitors. On RHEL 8, combining Nginx with a PHP-FPM backend and a well-configured cache can cut backend response times by 80–95% for cacheable pages. This tutorial walks through configuring the fastcgi_cache_path directive, defining cache keys, […]
Compression reduces the byte size of HTTP responses, lowering bandwidth consumption and improving page load times. Nginx ships with built-in Gzip support through ngx_http_gzip_module, but Gzip has largely been superseded by Brotli for text content — the Brotli algorithm typically achieves 15–25% better compression ratios at equivalent CPU cost. On RHEL 8, Gzip requires only […]
Rate limiting and connection throttling are essential defences against brute-force attacks, credential stuffing, and high-volume web scrapers. Nginx provides two built-in modules — ngx_http_limit_req_module for request-rate limiting and ngx_http_limit_conn_module for connection limiting — both compiled into the default binary. On RHEL 8 these capabilities are available immediately after installing Nginx from the AppStream module stream […]
ModSecurity is not limited to Apache — it can also protect Nginx deployments through a dedicated dynamic module called ngx_http_modsecurity_module. The module embeds the ModSecurity v3 library directly into Nginx’s request processing pipeline, enabling the same OWASP Core Rule Set that Apache users rely on. On RHEL 8, Nginx is available from the AppStream module […]
ModSecurity is a widely-deployed open-source Web Application Firewall (WAF) that integrates directly with Apache as a module. Combined with the OWASP Core Rule Set (CRS), it provides protection against the most common web attack categories including SQL injection, cross-site scripting, and remote code execution. On RHEL 8, both the mod_security Apache module and the mod_security_crs […]
Caddy is a modern, open-source web server written in Go that automatically provisions and renews TLS certificates via Let’s Encrypt. Unlike Apache or Nginx, Caddy requires almost no manual TLS configuration, making it an excellent choice for developers who want HTTPS out of the box. On RHEL 8, Caddy is not available in the default […]
Load balancing distributes incoming client requests across multiple backend servers, preventing any single server from becoming a bottleneck and improving both throughput and fault tolerance. Nginx’s built-in load balancing is highly capable and available in the open-source version without any additional modules for most common use cases. On RHEL 8, you can configure Nginx to […]
HTTP/2 delivers significant performance improvements over HTTP/1.1 through features such as header compression, request multiplexing, and server push — all over a single TCP connection. Nginx has supported HTTP/2 since version 1.9.5, and on RHEL 8 the AppStream version of Nginx is compiled with the necessary OpenSSL support to enable it. Because browsers only implement […]
Apache’s mod_proxy module turns your existing Apache web server into a fully functional reverse proxy without requiring a second web server like Nginx. This is particularly useful when you already have Apache managing SSL termination, virtual hosts, or authentication, and want to forward traffic to a backend application server such as Tomcat, Node.js, or a […]
Nginx is a high-performance web server that also excels as a reverse proxy, sitting in front of application servers and forwarding client requests to backend services running on internal ports. Using Nginx as a reverse proxy on RHEL 8 allows you to serve Node.js, Python, Java, or any HTTP-based application behind a clean public-facing endpoint […]
