Cache

Cache #

Currently all the images will be cached and served from cache after first request, unless a “Purge cache” is triggered or cache space is full, thus it’ll have the following features:

  • Works like “Always Online”, as long as the image cached, it can be normally rendered even if your Origin is offline.
  • You can cache all your images by manually request them through proxy, this is so called “cache pre-heat”

Cache status #

From each proxy’s detailed page, you can see all the request logs, the Cache Status indicates whether an images is being rendered by WebP Cloud’s cache.

  • Hit means rendered by WebP Cloud’s cache.

  • Miss means it’s not in WebP Cloud’s cache, and WebP Cloud has to fetch that original image to render

  • Dynamic means the vistor’s device doesn’t support WebP/AVIF format so the original image format is being served, for example, the png format image.
    • Here “original image” might both mean cached png image by WebP Cloud(like Hit), or WebP Cloud has fetched image(like Miss)
    • Rendered image will still be EXIF removed to avoid unwanted privacy exposure.

  • Filling means you’re using Rapid mode and cache Miss, and original image format is being rendered(while the image is being optimized by WebP Cloud).

You can find cache status in browser’s request too, for example, you can take a look at https://1e674d5.webp.li/pics/xishan-island/73.jpg images’s response header.

Cache Limit #

All Proxies for free user will have 200MiB of cache, if you go beyond that, we’ll use “Least Recently Used” (LRU) algorithm for eviction, that’s to say, the least-requested content will be evicted from cache.
