What is a CDN? India Edge Delivery Explained

What a CDN is — edge caching in plain words

A CDN is a ring of servers — points of presence (PoPs) — operated around the world that cache your site's static files close to visitors. A reader in Mumbai gets images from a Mumbai edge; only the uncached request travels to your origin server.

Key points:

• Static assets — images, CSS, JS — cache at the edge; dynamic pages still hit origin.

• Latency falls because round trips shrink: edge responses arrive in single-digit-to-tens of milliseconds.

• Origin bandwidth drops too, since edges serve the repeats.

• CDNs also absorb traffic spikes and basic attack noise at the edge.

• A CDN complements hosting — it cannot replace a slow origin.

Cloudflare's free plan is the standard first CDN for Indian sites, with local PoPs; setup takes minutes over cloud hosting origins. The speed hierarchy shows where the CDN sits among fixes; setup steps and honest limits follow below.

How it speeds up sites — the latency math

How this plays out with CDN: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.

CDN vs hosting vs DNS — untangled

Put a cache in front of pages that do not change per visitor, and keep cart, checkout and account pages uncached. After a DNS or cache change, test in a private window so your own browser cache does not lie. Lower the DNS TTL a day before a move, then raise it once the new target is confirmed.

Free tiers — Cloudflare for Indian traffic

On PoP (point of presence), the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.

Setting up Cloudflare with cPanel hosting

cPanel is the Linux control panel: files, mailboxes, databases, SSL and one-click installs live there. The login is separate from the WebJi® client area, where invoices and tickets live. If a mailbox exists in cPanel and mail still fails, check MX and the mail client ports before you recreate the account.

What not to cache — dynamic pages and cookies

On Cloudflare, the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.
