CDN (Content Delivery Network)

Webslice operates a global CDN that is turned on for your serverless websites by default, this speeds up page loads by serving static files from the edge.

The goal of the CDN is to speed up but not get in the way of your website, therefore Webslice will only cache static files in the CDN, no responses served by PHP will be cached, this allows us to handle invalidating the cache when a static file is updated.

You can configure the CDN caching strategy for your website in the Webslice Console under the Settings tab. There are a few different caching strategies available for your website:

Standard Caching

The Standard caching strategy only caches files with the following extensions:

7Z	APK	AVI	AVIF	BIN	BMP
BZ2	CLASS	CSS	CSV	DMG	DOC
DOCX	EJS	EOT	EPS	EXE	FLAC
GIF	GZ	ICO	ISO	JAR	JPG
JPEG	JS	MID	MIDI	MKV	MP3
MP4	OGG	OTF	PDF	PICT	PLS
PNG	PPT	PPTX	PS	RAR	SVG
SVGZ	SWF	TAR	TIF	TIFF	TTF
WEBM	WEBP	WOFF	WOFF2	XLS	XLSX
ZIP	ZST

All Static Caching

All Static caching will cache all static files regardless of their extension. This works well for public facing static websites that do not require any authentication or access control.

Caution

The All Static Caching strategy may interfere with any rules you have in your .htaccess file. If you are using .htaccess to control access to your website (e.g., htpasswd authentication or blocklists), the CDN will cache static files when they are requested and serve them to unauthenticated users, bypassing your .htaccess rules. In these cases, you should use the Standard Caching strategy or opt out of CDN caching entirely.

Disabling Caching

When this strategy is enabled, no files will be cached by the CDN.

You can also use one of the following cache control headers to opt out of CDN caching for particular responses:

Cache-Control: no-cache
Cache-Control: no-store
Cache-Control: private
