Souin is a new HTTP cache system suitable for every reverse-proxy. It can be either placed on top of your current reverse-proxy whether it's Apache, Nginx or as plugin in your favorite reverse-proxy like Træfik, Caddy or Tyk.
Since it's written in go, it can be deployed on any server and thanks to the docker integration, it will be easy to install on top of a Swarm, or a kubernetes instance.
It's RFC compatible, supporting Vary, request coalescing, stale cache-control and other specifications related to the RFC-7234.
It supports the newly written RFCs (currently in draft) http-cache-groups and http-invalidation.
It also supports the Cache-Status HTTP response header, the YKey group such as Varnish, the Targeted HTTP Cache Control RFC, .
It supports the ESI tags, thanks to the go-esi package.
Warning
Since v1.7.0
Souin implements only one storage. If you need a specific storage you have to take it from the storages repository and add it either in your code, during the build otherwise.
(e.g. with otter using caddy) You have to build your caddy module with the desired storage xcaddy build --with github.com/darkweak/souin/plugins/caddy --with github.com/darkweak/storages/otter/caddy
and configure otter in your Caddyfile/JSON configuration file.
See the storages section or the documentation website about the storages.
The configuration file is store at /anywhere/configuration.yml
. You can supply your own as long as you use one of the minimal configurations below.
default_cache: # Required
ttl: 10s # Default TTL
default_cache: # Required
ttl: 10s # Default TTL
reverse_proxy_url: 'http://traefik' # If it's in the same network you can use http://your-service, otherwise just use https://yourdomain.com
Key | Description | Value example |

default_cache.ttl |
Duration to cache request (in seconds) | 10 |
Besides, it's highly recommended to set default_cache.default_cache_control
(see it below) to avoid undesired caching for responses without Cache-Control
header.

All endpoints are accessible through the api.basepath
configuration line or by default through /souin-api
to avoid named route conflicts. Be sure to define an unused route to not break your existing application.
Prometheus API expose some metrics about the cache.
The base path for the prometheus API is /metrics
.
Not supported inside Træfik because the deny the unsafe library usage inside plugins
Method | Endpoint | Description |

Souin API allow users to manage the cache.
The base path for the souin API is /souin
.
The Souin API supports the invalidation by surrogate keys such as Fastly which will replace the Varnish system. You can read the doc about this system.
This system is able to invalidate by tags your cloud provider cache. Actually it supports Akamai and Fastly but in a near future some other providers would be implemented like Cloudflare or Varnish.
Method | Endpoint | Headers | Description |
---|---|---|---|
GET |
/ |
- | List stored keys cache |
GET |
/surrogate_keys |
- | List stored keys cache |
PURGE |
/{id or regexp} |
- | Purge selected item(s) depending. The parameter can be either a specific key or a regexp |
PURGE |
/?ykey={key} |
- | Purge selected item(s) corresponding to the target ykey such as Varnish (deprecated) |
PURGE |
/ |
Surrogate-Key: Surrogate-Key-First, Surrogate-Key-Second |
Purge selected item(s) belong to the target key in the header Surrogate-Key (see Surrogate-Key system) |
PURGE |
/flush |
- | Purge all providers and surrogate storages |
DEPRECATED
Security API allows users to protect other APIs with JWT authentication.
The base path for the security API is /authentication
.
Method | Endpoint | Body | Headers | Description |
---|---|---|---|---|
POST |
/login |
{"username":"admin", "password":"admin"} |
['Content-Type' => 'json'] |
Try to login, it returns a response which contains the cookie name souin-authorization-token with the JWT if succeed |
POST |
/refresh |
- |
['Content-Type' => 'json', 'Cookie' => 'souin-authorization-token=the-token'] |
Refreshes the token, replaces the old with a new one |
See the sequence diagram for the minimal version below
Supported providers
The cache system sits on top of three providers at the moment. It provides two in-memory storage solutions (badger and nuts), and two distributed storages Olric and Etcd because setting, getting, updating and deleting keys in these providers is as easy as it gets.
The Badger provider (default one): you can tune its configuration using the badger configuration inside your Souin configuration. In order to do that, you have to declare the badger
block. See the following json example.
"badger": {
"configuration": {
"ValueDir": "default",
"ValueLogFileSize": 16777216,
"MemTableSize": 4194304,
"ValueThreshold": 524288,
"BypassLockGuard": true
}
}
The Nuts provider: you can tune its configuration using the nuts configuration inside your Souin configuration. In order to do that, you have to declare the nuts
block. See the following json example.
"nuts": {
"configuration": {
"Dir": "default",
"EntryIdxMode": 1,
"RWMode": 0,
"SegmentSize": 1024,
"NodeNum": 42,
"SyncEnable": true,
"StartFileLoadingMode": 1
}
}
The Otter provider: you can tune its configuration using the otter configuration inside your Souin configuration. In order to do that, you have to declare the otter
block. See the following json example.
"otter": {
"configuration": {
"size": 9999999
}
}
The Olric provider: you can tune its configuration using the olric configuration inside your Souin configuration and declare Souin has to use the distributed provider. In order to do that, you have to declare the olric
block and the distributed
directive. See the following json example.
"distributed": true,
"olric": {
"configuration": {
# Olric configuration here...
}
}
In order to do that, the Olric provider need to be either on the same network as the Souin instance when using docker-compose or over the internet, then it will use by default in-memory to avoid network latency as much as possible.
The Etcd provider: you can tune its configuration using the etcd configuration inside your Souin configuration and declare Souin has to use the distributed provider. In order to do that, you have to declare the etcd
block and the distributed
directive. See the following json example.
"distributed": true,
"etcd": {
"configuration": {
# Etcd configuration here...
}
}
In order to do that, the Etcd provider need to be either on the same network as the Souin instance when using docker-compose or over the internet, then it will use by default in-memory to avoid network latency as much as possible. Souin will return at first the response from the choosen provider when it gives a non-empty response, or fallback to the reverse proxy otherwise. Since v1.4.2, Souin supports Olric and since v1.6.10 it supports Etcd to handle distributed cache.
This feature is currently in beta.
Souin can partially cache your GraphQL requests. It automatically handles the data retrieval and omit the caching for the mutations.
However, it will invalidate whole cache keys with a body when you send a mutation request due to the inability to read and understand automatically which cached endpoint should be deleted.
You can enable the GraphQL support with the default_cache.allowed_http_verbs
key to define the list of supported HTTP verbs like GET
, POST
, DELETE
.
default_cache:
allowed_http_verbs:
- GET
- POST
- HEAD
The cache invalidation is built for CRUD requests, if you're doing a GET HTTP request, it will serve the cached response when it exists, otherwise the reverse-proxy response will be served.
If you're doing a POST, PUT, PATCH or DELETE HTTP request, the related cache GET request, and the list endpoint will be dropped.
It also supports invalidation via Souin API to invalidate the cache programmatically.
To use Souin as beego filter, you can refer to the Beego filter integration folder to discover how to configure it.
You just have to define a new beego router and tell to the instance to use the Handle
method like below:
import (
"net/http"
httpcache "github.com/darkweak/souin/plugins/beego"
)
func main(){
// ...
web.InsertFilterChain("/*", httpcache.NewHTTPCacheFilter())
// ...
}
To use Souin as caddy module, you can refer to the Caddy module integration folder to discover how to configure it.
The related Caddyfile can be found here.
Then you just have to run the following command:
xcaddy build --with github.com/darkweak/souin/plugins/caddy

[roadrunner]
ref = "master"
[github]
[github.token]
token = "GH_TOKEN"
[github.plugins]
logger = { ref = "master", owner = "roadrunner-server", repository = "logger" }
cache = { ref = "master", owner = "darkweak", repository = "souin", folder = "/plugins/roadrunner" }
# others ...
[log]
level = "debug"
mode = "development"
After that, you'll be able to set each Souin configuration key under the http.cache
key.
# .rr.yaml
http:
# Other http sub keys
cache:
api:
basepath: /httpcache_api
prometheus:
basepath: /anything-for-prometheus-metrics

To use Souin as skipper filter, you can refer to the Skipper plugin integration folder to discover how to configure it.
You just have to add to your Skipper instance the Souin filter like below:
package main
import (
souin_skipper "github.com/darkweak/souin/plugins/skipper"
"github.com/zalando/skipper"
"github.com/zalando/skipper/filters"
)
func main() {
skipper.Run(skipper.Options{
Address: ":9090",
RoutesFile: "example.yaml",
CustomFilters: []filters.Spec{souin_skipper.NewSouinFilter()}},
)
}
After that you will be able to declare the httpcache filter in your eskip file.
hello: Path("/hello")
-> httpcache(`{"api":{"basepath":"/souin-api","security":{"secret":"your_secret_key","enable":true,"users":[{"username":"user1","password":"test"}]},"souin":{"security":true,"enable":true}},"default_cache":{"regex":{"exclude":"ARegexHere"},"ttl":"10s","stale":"10s"},"log_level":"INFO"}`)
-> "https://www.example.org"
To use Souin as Træfik plugin, you can refer to the pilot documentation and the Træfik plugin integration folder to discover how to configure it.
You have to declare the experimental
block in your traefik static configuration file. Keep in mind Træfik run their own interpreter and they often break any dependances (such as the yaml.v3 support).
# anywhere/traefik.yml
experimental:
plugins:
souin:
moduleName: github.com/darkweak/souin
version: v1.7.5
After that you can declare either the whole configuration at once in the middleware block or by service. See the examples below.
