Loki

About

Loki allows site builders to configure simulated random server error responses.

What's a Loki?

Loki is a trickster god of Norse mythology --

He’s by turns playful, malicious, and helpful, but he’s always irreverent and nihilistic.

This module fits that description quite nicely in that it is somewhat playful and, in a way, malicious but can also be a helpful way to test and verify origin and edge configurations with a Drupal application.

Requirements

None.

Installation

Install as you would normally install a contributed Drupal module. See Installing Modules for more information.

Configuration

Visit Configuration » Development » Loki (/admin/config/development/loki) to enable and configure module settings.

Functionality

This module allows the site builder to configure a percent chance (per request) for certain configurable user roles to receive certain configurable error responses (in the 5XX range) from the server during any response.

Use Cases

The primary use case this module is developed for is specific and ongoing testing of CDN and proxy servers. The functionality of this module is particularly useful for testing Stale-If-Error configuration between origin and proxy servers.
