Hello,
I think you can add an image optimiser to Souin with return jpeg/wepb depending on accept header provided by the client like this : https://github.com/agravelot/traefik-image-optimization

Hi @darkweak ,

Hope you are all well !

I was wondering if it would be an interesting feature to use Souin as an acme CDN (Content Delivery Network) for static assets like js/css and medias.

Use case:

• Dropin media server for Prestashop websites (1M installs)

Thanks for any insights or inputs about that.

Cheers,
Luc Michalski

Issue

Hey ! Sorry to create an issue but I'm having problems configuring Souin with Traefik.

First of all, thanks for the awesome project ! It's a great tool to now go fully Traefik with caching features (instead of using Haproxy).

Here goes the error. When I disable Souin, everything works fine and I can access my homeassistant remotely with correct certs generated by Lets encrypt etc. However, as soon as I configure Souin, I keep getting the errors below. My configuration is available below too.

reverse-proxy-http-cache    | {"level":"DEBUG","time":"2021-07-18T08:59:42.764Z","caller":"plugins/base.go:105","message":"Provider initialized"}

reverse-proxy-http-cache    | 2021/07/18 08:59:56 http: TLS handshake error from XXX:58728: remote error: tls: bad certificate

I tried disabling the redirection from http to https in Traefik but it didn't change anything. I'm using network_mode: host as I have some requirements for the homeassistant for that. In case you are wondering, I'm copying the configuration.yml using Dockerfile.

Any idea why this fails ? Maybe it doesn't resolve to localhost:81 ? I've checked using netstat and Traefik is available on port 81 & 444 in the host network. I've also checked the acme.json file and its filled & it's available in the souin container at the specified path.

Thanks for your time !

Refer to the TykTechnologies/tyk#3583

Current enhancement below:

• Write the Tyk adapter
• Build .so extension file using the Tyk container
• Testing before merge
• Update the release CI to ensure everything works fine for this plugin

While testing this, I noticed that a 404 response comes back as 404 before being cached and then after being cached is being presented as 200. Shouldn't it present the 404 response status code instead?

A question following from this : is it possible to only cache results with 200 response status codes?

• Better cache speed
• Hot reload config
• Config by reference instead of copy
• Less heavy binary removing unused deps

Lightweight Souin instance for

• Træfik plugins

Implementation

• RFC compliant 100%

We have to define a storage that will store uncacheable requests and we will check this storage if an incomming can be eventually marked as cacheable and enable the coalescing for this, then don't try to coalesce them

We have to use a second storage layer to be able to map varied headers with the following pattern
{baseKey}-[{header1};{header2};{...}]

Then we'll be able to store varied requests without poisoning it with another varied requests

Support Apache dynamic SSL like Træfik implementation.
Maybe create an external script to aggregate different certificates passing an array of string containing string path (real path or relative?)

• Setup docker image build
• Add golang code coverage over 50%
• Add gatling tests
• Update documentation to use docker image
• Add examples

Hi @darkweak ,

Hope you are all well !

It would be awesome to create a filter on the user-agent to cache page per device types (desktop/tablet and mobile) like varnish plugin https://github.com/varnishcache/varnish-devicedetect.

It is just a collection of regexrules for setting up a prefix to cache key.

What do you think about that ? Does it inspire you an easy way to implement this layer ?

We want to be able to define the cache TTL depending either one of URL, Headers or Cookies or every ones at the same time.
We could replace the MatchedURL object to another one, like CacheKey with the following structure

type CacheKey struct {
    type  string (eg."headers"|"cookies")
    regex string
}

Or another one with a priority field

type CacheKey struct {
    url      string (eg."/^.+$/")
    cookies  string (eg."/^.+$/")
    priority int
}

Then the YAML could be one of

cache_keys:
  - type: headers
    regex: '/^.+$/'
  - type: cookies
    regex: '/^.+$/'
  - type: headers
    regex: '/^[A-z]+$/'

cache_keys:
  - cookies: '/^.+$/'
    priority: 1
  - url: '/^.+$/'
    priority: 40
  - url: '/nothing$/'
    cookies: '/^Auth.+$/'
    priority: 999

Provide a REST API to be able to :

• Use BAN/PURGE HTTP methods
• Clear keys by regexp

API will be accessible with or without JWT depending your configuration

Hi @darkweak ,

Hope you are all well !

So, I am looking for an alternative to varnish for caching content of some prestashop websites.

What is the state of souin vs varnish ? Do you plan to have an advanced config file for parsing cookies or headers for custom caching ?

Thanks for any insights or inputs on that.

Cheers,
Luc Michalski

Restrict to master and full-version to be able to be tagged as new version and deploy artifacts

• Add E2E tests
• Check E2E on CI
• Improve test suite

To prevent build failed and ensure users can build the containers on their environment

Implement Olric as available provider based on provider interface

Hi @darkweak ,

Hope you are all well !

I wanted also tyo suggest the creation of grafana dashboard with a prometheus exporter.

For my part, I am using a gin-gonic/prometheus middleware for feeding a grafana dahsboard. It also use a geoip2 middleware for a world map panel.

We want to be able to detect the vary requests with only one request to the storage system.
Obviously it will change the key generation.

The base generated key won't be affected. If the response doesn't contain the vary header with the varied list then the key will be like {request.method}-{request.host}-{request.uri}.
If the response contains the vary header with the varied headers list it will be like this one {request.method}-{request.host}-{request.uri}{-VARY-}{first varied header key}:{first varied header value};{second varied header key}:{second varied header value}.

With that, we will be able to request the storage and retrieve the associated (varied or not) responses, thanks to the prefix query.

Hi, Currently trying to get a simple working example. I've read the (quite sparse) doc, saw this post and went through following slides.

I am using following configuration (the simplest one up to the doc):

default_cache: # Required part
  port: # Ports to expose Souin
    web: 80
  ttl: 10 # Default TTL
reverse_proxy_url: 'http://localhost'

I am running following Docker Compose configuration:

version: '3.7'

services:

  traefik:
    image: traefik:latest
    command:
      - "--api.insecure=true"
      - "--providers.docker=true"

So what am I doing wrong? Is this project used at all (googling for souin and traefik does not return that much help/matches)?

Thanks and have a beautiful day.

We want to support Souin as Caddy 2 plugin to be able to use this inside Caddy instance instead of on top of this reverse-proxy
