# X-Frame-Options is a HTTP header supported by modern browsers. | ||

# Web applications can send this header to prevent Clickjacking attacks. | ||

# Content-Security-Policy (CSP) is a HTTP header supported by modern | ||
# browsers. It determines trusted sources of execution for dynamic | ||
# contents (JavaScript) or other web related assets: stylesheets, images, | ||
# fonts, plugins, etc. | ||
# | ||
# Web applications can send this header to mitigate Cross Site Scripting | ||
# (XSS) attacks. | ||
# | ||
# The default value allows images, scripts, AJAX, fonts and CSS from the | ||
# same origin, and does not allow any other resources to load (eg object, | ||
# frame, media, etc). | ||
# | ||
# Inline JavaScript is NOT allowed. To enable it, please use: | ||
# "script-src 'unsafe-inline'". | ||
