A CDN, or content delivery network, is a group of servers spread across many locations that store copies of website content closer to visitors. It speeds up page loading by serving files from a server near the user instead of a single, distant origin server.
When a website uses a CDN, copies of its images, scripts, and other static files get stored on servers, called edge nodes, located in data centers around the world. A visitor requesting the site gets served from the nearest edge node instead of the original server, which cuts down the distance the data has to travel. CDNs also help absorb traffic spikes, since the load spreads across many servers instead of hitting one origin server directly. Because CDNs often route traffic differently by region, users connecting through a proxy may get served from a different edge node than they would from their real location.
Most proxy users only need to understand this well enough to debug it, not configure it directly.

Measure this metric without a proxy first, so you know what the gateway adds versus what was already there.
This concept governs the connection to the gateway and the gateway to the target -- check both when something looks wrong.
KnoxProxy manages this at the infrastructure layer, so most jobs only need to understand it well enough to debug.
A new ISP, VPN, or office network can change how this behaves -- confirm it again after any local network change.
A user connecting through a proxy in another country loads a website faster because the CDN serves the page from a nearby edge server in that region.
CDNs affect how proxy users experience website speed, since the proxy IP location determines which edge server responds to the request. Understanding CDN behavior helps explain why the same site can load at different speeds depending on which proxy location is used.
Some CDNs maintain IP reputation databases and can flag known proxy or datacenter IP ranges, which may trigger extra verification steps like CAPTCHAs. Residential proxy IPs are generally less likely to be flagged this way.
Yes, since the CDN typically routes a visitor to the nearest edge server based on IP location, connecting through a proxy in another region can change which edge server responds and how fast the page loads.
