Varnish

Varnish is an HTTP accelerator, often called a full-page cache. It sits in front of your web server and serves stored copies of pages in milliseconds, so the application only builds a page when something has changed. It is the cache Magento recommends for production stores.

How we use Varnish

• Installing and configuring Varnish for Magento and other high-traffic PHP applications.
• Writing cache rules (VCL) so personalised content, carts and logged-in pages stay correct.
• Setting up cache purging so price and stock changes appear instantly.
• Load-testing stores before sales and festive seasons to confirm they stay fast under pressure.

When Varnish is the right choice

Varnish is worth it for busy stores and content sites where the same pages are requested many times. On managed hosting with built-in caching, such as LiteSpeed, a separate Varnish layer may not be needed. We look at your traffic and hosting before recommending it.

Frequently asked questions

Will Varnish show customers the wrong prices or cart contents?

Not when configured correctly. Personal elements such as carts and customer names are loaded separately or excluded from the cache, and prices are purged from the cache as soon as they change in the admin.

How do I know Varnish is working?

Response headers show whether a page was served from the cache, and monitoring shows the hit rate. We share these checks during handover so your team can confirm caching after changes or deployments.
