This guide walks you through Squid's features, how it works, hardware requirements, step‑by‑step installation, default and custom configuration, initialization, testing, and detailed ACL examples to control access and improve network performance on Linux systems.
This guide walks you through setting up a Squid proxy on Linux, configuring Jenkins to use the proxy, adding a domestic plugin repository, and adjusting firewall rules, enabling reliable network connectivity and plugin installation for Jenkins in environments with restricted internet access.
This guide walks through installing Squid on Linux, configuring it as a transparent proxy for internal clients, setting up a reverse proxy for external web servers, and applying common ACL rules to control access and improve network performance.
This guide explains how to expose an internal‑only server to the Internet by deploying Squid HTTP and HTTPS proxies on two public servers, configuring stunnel on the client, adjusting firewall rules, and testing connectivity for both ports.
This guide walks you through installing Squid on Linux, configuring caching, ACLs, and network settings, troubleshooting startup issues, and testing the proxy to improve bandwidth usage and enforce access control for your internal users.
This guide walks through installing Squid on Linux, configuring it as a transparent and reverse proxy, setting up internal and external hosts, adjusting routing and firewall rules, and applying common ACL parameters to control access and improve performance.
This guide explains how to make an internal IDC server reachable from the public Internet for both HTTP and HTTPS by deploying two public servers with Squid proxies and configuring stunnel on the client, including detailed command‑line steps for Linux and Ubuntu.
This tutorial demonstrates how to configure an open‑source Squid proxy in an AWS VPC to restrict Internet access, allow only approved Amazon S3 buckets and Yum repositories, route traffic through specific gateways, and achieve high availability using Auto Scaling and Route 53.
This guide walks through what Squid is, its traditional and transparent proxy modes, step‑by‑step installation, configuration of cache directories, service scripts, temporary and permanent proxy settings on Linux, and notes on using Squid as a unified outbound gateway.
This tutorial walks you through installing the GD library, building SARG from source, configuring its key parameters, running reports, using command‑line options, scheduling automated jobs with cron, and troubleshooting common installation and configuration issues for Squid log analysis.
This guide explains how to set up Squid as an explicit or implicit forward proxy on Linux, covering SSL/TLS termination, required build tools, user creation, compilation options, CA generation, detailed squid.conf settings, and necessary iptables NAT rules.
This article explains the fundamentals of CDN, introduces QunarCache (CDN + Cache) architecture, compares cache solutions such as Squid, Varnish, ATS and Nginx, describes deployment patterns, operational monitoring, and future improvements for scalable, resilient content delivery.
This guide walks you through creating an AWS EC2 instance, installing and configuring Squid as a proxy, restarting the service, setting up local proxy settings, and securing the connection with an SSH tunnel for encrypted traffic.
Varnish and Squid are open‑source reverse proxy cache servers, but Varnish generally outperforms Squid with higher stability, faster memory‑based caching, greater concurrent connections, and regex‑based cache invalidation, while its higher CPU, I/O, and memory usage and loss of cache on failure can be drawbacks.
This article explains how to set up a Linux Squid proxy that injects malicious JavaScript into every served script, captures user input, forces persistent caching, and outlines the severe security risks such as credential theft, financial fraud, DDoS abuse, and full browsing surveillance.
This article explains how Linux's built‑in tmpfs (mounted at /dev/shm) can be leveraged for high‑speed caching and PHP session storage, detailing its advantages, setup steps, and practical examples with Squid and PHP to improve system performance.
