Technically speaking, a CDN is a reverse proxy network. So yes, a CDN is a kind of proxy. But its direction and purpose are the exact opposite of what we call a "proxy" in everyday language.
The Difference in Direction
A forward proxy hides the user and speaks on their behalf. A CDN protects and accelerates the server and responds on its behalf.
Comparison
The same technology (an intermediary server) serving two different sides. That is why the question "proxy or CDN" is usually the wrong question.
For the technical details of the forward and reverse distinction, see the difference between forward and reverse proxies article.
Running into a CDN While Collecting Data
If you are collecting data from a site, what you face is almost always a CDN rather than the origin server. This directly affects behavior:
The CDN's bot management looks at IP reputation and behavior patterns. That is why the choice of IP type and the request rate are decisive on sites behind a CDN.
Do not try to "bypass" the CDN cache — adding random query parameters usually triggers bot detection. If you need fresh data, looking for the site's official API is far more efficient.
Geographic Routing
A CDN routes the user to the nearest edge node and in some cases serves region-specific content. This means your proxy exit location directly affects the result:
This is a critical detail for businesses that track regional prices and campaigns. For location options, see see our locations page .
If You Use a CDN on Your Own Site
The other side of the coin: if your own site is behind a CDN, you have to look at the headers the CDN adds in order to read the real visitor IP. Trust those headers only once you have verified that they came from your CDN — otherwise you will accept spoofed values. We covered the topic in our article on headers in detail.
Summary
Technically a CDN is a reverse proxy network; it uses the same underlying technology as a forward proxy, in the opposite direction. When you collect data, what you face is almost always a CDN, and this shows up as bot protection, geographic routing and cache behavior. Exiting from the right region and keeping your request rate reasonable are the two basic conditions for success on sites behind a CDN. For the right proxy type, see residential or ISP proxy pages.
