Simple, lightweight and ultra-fast HTTP Cache to speed up your websites.

Requirements

Features:

General

To known if request pass across Kratgo Cache in backend servers, check the request header X-Kratgo-Cache with value true.

Install

Clone the repository:

git clone https://github.com/savsgio/kratgo.git && cd kratgo

and execute:

make
make install

The binary file will install in /usr/local/bin/kratgo and configuration file in /etc/kratgo/kratgo.conf.yml

Cache invalidation (Admin)

The cache invalidation is available via API. The API's address is configured in admin section of the configuration file.

This API only accepts POST requests with json, under the path /invalidate/.

Ex: http://localhost:6082/invalidate/

The complete json body must be as following example:

{
	"host": "www.example.com",
	"path": "/es/",
	"header": {
		"key": "Content-Type",
		"value": "text/plain; charset=utf-8"
	}
}

IMPORTANT: All fields are optional, but at least you must specify one.

All invalidations will process by workers in Kratgo. You can configure the maximum available workers in the configuration.

The workers are activated only when necessary.
