027 | Proxy Servers: Your Reliable Network Middleman — Why You Need Them and How They Work

2025-06-19

In today’s internet-driven world, where data constantly travels between millions of devices, it’s often not enough to establish a direct connection — you may need a “middleman.” That’s where a proxy server comes in. It acts as a bridge between you (the client) and the destination resource (server), handling network requests on your behalf. Understanding how proxies work is critical for network security, optimization, and access management.


What is a Proxy Server?

A proxy server (from the English proxy — representative, intermediary) is a server in a computer network that acts as an intermediary between a user (client) and other internet servers. All client requests go through the proxy first, which then forwards them to the destination server. Responses from the destination server also return to the proxy first before being sent back to the client.

I want to express my deep gratitude to the specialist who set up SEO-friendly URLs for me on OpenCart.

Answer: Thank you for the detailed review! I look forward to further cooperation.

I needed to resolve an SSL certificate issue on a server where the certificate had been issued through Nginx Proxy Manager. Mikhail clarified all the details of my setup and requested access to assess the feasibility of solving the issue, since he hadn't worked with that service before. He quickly figured it out and fixed my problem. Perfect cooperation)

Resolving 5XX errors on the website

0001-01-01

I will perform a full audit and fix 5XX errors on the site:

  • 500 Internal Server Error
  • 502 Bad Gateway
  • 503 Service Unavailable
  • 504 Gateway Timeout

I will check configurations of Nginx/Apache, PHP-FPM, database and eliminate the root causes of the failures.
I will set up optimizations so these errors do not recur.
Result — a stable site without crashes or hidden issues.
