S-Cache Header Explained

Whenever you use our smoxy with Acceleration or Image Optimization enabled, you will encounter the S-Cache header related to caching. This header indicate the cache status across different layers of our content delivery infrastructure.

HIT

The resource was found in smoxy's cache.

MISS

The resource was not found in smoxy's cache and was served from the origin web server.

BYPASS

When the Cache Control Header configuration was enabled in the basic configuration and the origin web server instructed smoxy to bypass cache via a Cache-Control header set to no-cache, private, or max-age=0 .

BYPASS is also returned if your request to your origin web server includes an http-bypass header with a valid token or a base64 encoded string of your hostname.

When the returned content type of your request is not eligible for caching, smoxy will also return BYPASS.
