## Popis

EssentialHeaders is a focused WordPress plugin that attaches the HTTP security headers
browsers expect, so protection is not left to chance or buried in server config.

Under Settings  EssentialHeaders you get three tabs:

 * Headers — overview of which headers are enabled and will be sent
 * Settings — toggles and editable values for each header
 * About — plugin info

Headers covered:

 * Content-Security-Policy (CSP)
 * Strict-Transport-Security (HSTS)
 * X-Frame-Options
 * X-Content-Type-Options
 * Referrer-Policy
 * Permissions-Policy

Safer headers ship enabled with sensible defaults. CSP starts off so you can adopt
it deliberately. Headers apply to public site responses (pages, feeds, and the login
screen)—not wp-admin, AJAX, REST, GraphQL, or XML-RPC. HSTS is only sent over HTTPS.
Default HSTS uses max-age only; add includeSubDomains yourself when every subdomain
is ready.

## Instalace

 1. Upload the `essentialheaders` folder to the `/wp-content/plugins/` directory.
 2. Activate the plugin through the Plugins menu in WordPress.
 3. Open Settings  EssentialHeaders to review and configure headers.

## Nejčastější dotazy

### Will this break my site?

The default set is conservative. Content-Security-Policy is off by default because
a strict CSP can block scripts or styles your theme needs. Enable CSP when you are
ready to tune it.

### Does HSTS work on HTTP?

No. Strict-Transport-Security is only sent when the visitor reaches the site over
HTTPS.

### Does the login screen get these headers?

Yes. The login screen is treated as a public response. wp-admin, AJAX, REST, GraphQL,
and XML-RPC are excluded so dashboards and APIs are not broken by a strict CSP.

### Does this change site content?

No. The plugin only stores its own options and adds HTTP response headers on public
responses.

## Přehled změn

#### 1.0.1

 * Fix: always send security headers on front-end HTML even when the request Accept
   header prefers JSON. Skipping those requests let page caches store header-less
   responses and broke scanner results after cache warm-up.

#### 1.0.0

 * Initial release.
