The term virtual host refers to running two different sites on the same machine. This allows one server to share the same resources to multiple sites. There are two types of virtual hosting-name based and IP-based. Name-based hosts use multiple hostnames for the same IP address. The main issue with name-based virtual hosting is that it is difficult to host multiple websites running under secure SSL/TLS protocol. Also if DNS is not functioning, there will be some difficulties to access virtually hosted website even if the IP address is known, …

Bandwidth throttling is a deliberate technique used to control the amount of data that can be transferred over a network within a specific time period. It is commonly applied by internet service providers, hosting environments, firewalls, and applications to manage network congestion, maintain stability, and ensure fair usage of resources. While throttling is often misunderstood as general website slowness, it is important to distinguish intentional bandwidth limits from performance bottlenecks caused by inefficient code or server overload. What Is Bandwidth Throttling? Bandwidth throttling refers to the intentional limitation of upload …

SNI ( Server Name Identification) allows you to host multiple SSL certificates on a single IP address. Although, hosting several sites on a single virtual private server is possible with the use of virtual hosts, providing separate SSL certificates for each site traditionally required separate IP addresses. The process has now been simplified through the use of Server Name Indication (SNI), which sends a site visitor the certificate that matches the requested server name. Requirements 1. Domain names should be registered in order to serve the certificates by SNI. 2. …
A completely frozen Linux system can be frustrating. The mouse cursor does not move. Keyboard shortcuts like Ctrl + Alt + F1 or Ctrl + Alt + Backspace do not respond. Even the Num Lock key may stop toggling. In such situations, most users force a hard reset. However, a hard reboot can lead to data corruption or filesystem damage. There is a safer way to reboot a locked Linux system using the Magic SysRq key. This method allows you to properly terminate processes, sync disks, and safely reboot the …
mod_fcgid is a high-performance Apache module designed to improve the execution of CGI applications. It was introduced as a binary-compatible replacement for FastCGI while providing better control over process management and resource usage. Unlike traditional CGI modules such as mod_cgi or mod_cgid, mod_fcgid keeps application processes running in the background, allowing them to handle multiple requests efficiently without restarting for every connection. Why Use mod_fcgid? mod_fcgid offers several advantages: Installing mod_fcgid Step 1: Install Apache Components On Red Hat or CentOS systems, install Apache with the threaded MPM Worker module …
