CDN Integration

CDN integration places copies of your images, scripts and downloads at locations nearer your visitors. Cache headers take the bulk of the effort, since incorrect ones cause stale pages.

What belongs on the network

Static files are the simple case. Pages and personal data need more thought before anything is cached at the edge.

Images and media

Product photographs, catalogues and brochures, which usually make up most of what a page downloads.

Scripts and styles

Versioned filenames mean a new release is picked up immediately and does not wait out an old copy.

Never the private

Invoices, dashboards and anything behind a login stay off the edge unless the rules have been checked carefully.

Getting the headers right

Most CDN problems are header problems. The network is doing what it was told.

Long life, new names

Assets are cached for a long time and renamed on each release, so a deployment appears at once.

Purge on change

A file can be cleared deliberately, for the day someone replaces an image under the same name.

Compression at the edge

Text assets are compressed and served in modern formats, which matters most on a weak mobile connection.

What a CDN does not do

A CDN is often sold as a speed cure, and it is not one. Measurement shows where the seconds really are.

Slow server answers

If your application takes four seconds to build a page, a delivery network delivers that delay faster.

Heavy queries

Nothing at the edge helps a report that reads a full table. That work belongs in the database.

Oversized images

A five megabyte photograph stays five megabytes when served from a nearby location. Resize it first.

FAQ

Frequently asked questions

Do we need a CDN if all our customers are in one country?

It depends on your pages and your audience. Most providers have locations in many countries, so the gain within one country is real, but a small site with light pages may see a difference too small to matter.

Will a CDN protect us from traffic spikes?

Partly. It absorbs requests for static files, which helps during a campaign. Dynamic pages still reach your server, so a sale day also needs caching and load testing behind the network.

Which CDN do you set up?

Cloudflare most often, plus the cloud providers’ own networks where you already host on AWS or Azure. The choice follows your hosting.
