srv-web-7-7-inj-logout
This role injects a catcher that intercepts all logout elements in HTML pages served by Nginx and redirects them to a centralized logout endpoint via JavaScript.
Description
The srv-web-7-7-inj-logout
Ansible role automatically embeds a lightweight JavaScript snippet into your web application's HTML responses. This script identifies logout links, buttons, forms, and other elements, overrides their target URLs, and ensures users are redirected to a central OIDC logout endpoint, providing a consistent single sign‑out experience.
Overview
- Detection: Scans the DOM for anchors (
<a>
), buttons, inputs, forms,use
elements and any attributes indicating logout functionality. - Override: Rewrites logout URLs to point at your OIDC provider’s logout endpoint, including a redirect back to the application.
- Dynamic content support: Uses a
MutationObserver
to handle AJAX‑loaded or dynamically injected logout elements. - CSP integration: Automatically appends the required script hash into your CSP policy via the role’s CSP helper.
Features
