This article explains what internal network penetration is, why developers should use FRP (Fast Reverse Proxy) to access internal services, perform remote debugging, receive webhooks, protect sensitive data, and provides a step‑by‑step guide to install and configure FRP on Linux servers and clients.
This guide shows how to configure Nginx to proxy both unsecured WebSocket (ws) and secure WebSocket (wss) traffic, using standard HTTP ports 80 and 443, by setting upgrade headers, defining upstream servers, and adding SSL certificates for encrypted connections.
This article explains how front‑end projects access back‑end services after deployment, how Nginx reverse‑proxy solves cross‑origin problems, and how to configure production paths in Vue projects for proper static resource delivery.
This guide explains how to configure Nginx to forward the original client IP using X-Real-IP or X-Forwarded-For headers and provides Java servlet code to reliably extract that IP on the backend.
This article walks through a real‑world Nginx reverse‑proxy SSL issue, explains the root cause of 502 and handshake failures caused by missing SNI support, and provides step‑by‑step configuration changes and code snippets to resolve the problem.
This tutorial explains how to set up Nginx Proxy Manager using Docker, covering its key features, Docker‑Compose installation, login credentials, configuring a reverse proxy for a backend interface, obtaining Let’s Encrypt SSL certificates, and enabling HTTPS access.
This guide shows how to generate self‑signed certificates with OpenSSL, configure Nginx as an HTTPS reverse proxy in a Docker container, install the root certificate, and adjust the hosts file so front‑end code can securely call local services during development.
This article explains how a host‑level Nginx reverse proxy and a Kubernetes nginx‑ingress pod work, detailing their configuration files, the role of Ingress resources, and how traffic is routed to service endpoints within a cloud‑native environment.
This article explains how a Kubernetes nginx‑ingress pod acts as a gateway, converting Ingress YAML definitions into Nginx reverse‑proxy settings, detailing host‑level and pod‑level configurations, deployment manifests, service exposure, and scaling considerations.
This article explains how traditional host‑based Nginx reverse‑proxy configurations compare with the nginx‑ingress controller running as a pod in Kubernetes, detailing their setup, deployment YAML, ingress resources, and generated Nginx configuration for exposing services.
This article explains the capabilities of Nginx without third‑party modules, covering reverse proxy, load balancing strategies, static HTTP serving, dynamic/static separation, and forward proxy, and provides concrete configuration examples for each feature.
This guide explains Nginx’s core concepts—including forward and reverse proxy, load‑balancing strategies, static‑dynamic separation, installation commands, configuration file anatomy, practical reverse‑proxy and load‑balancing examples, and a Keepalived high‑availability solution—providing step‑by‑step instructions and essential code snippets for reliable backend deployment.
This article explains how host‑level Nginx and the nginx‑ingress pod work as reverse proxies, how Ingress YAML definitions are converted into Nginx configuration, and how to expose services via NodePort for scalable traffic handling in Kubernetes.
This guide shows how to add HTTPS to an internal web service by either routing traffic through Nginx as a reverse proxy or configuring FRP itself with SSL certificates, including detailed server (frps) and client (frpc) settings, firewall tips, and verification steps.
This comprehensive guide walks you through configuring Nginx status pages, compiling modules, using built‑in and custom variables, setting up JSON and gzip logs, enabling HTTPS, mastering rewrite rules, preventing hotlinking, implementing reverse proxy with caching, and deploying both HTTP and TCP load‑balancing with Redis and MySQL back‑ends.
