NAME

Amon2::Plugin::Web::CSRFDefender - Anti CSRF filter

SYNOPSIS

    package MyApp::Web;
    use Amon2::Web;

    __PACKAGE__->load_plugin('Web::CSRFDefender');

DESCRIPTION

This plugin denies CSRF request.

Do not use this with HTTP::Session2. Because HTTP::Session2 has XSRF token management function by itself.

METHODS

$c->get_csrf_defender_token()

Get a CSRF defender token. This method is useful to add token for AJAX request.

$c->validate_csrf()

You can validate CSRF token manually.

PARAMETERS

no_validate_hook

Do not run validation automatically.

no_html_filter

Disable HTML rewriting filter. By default, CSRFDefender inserts XSRF token for each form element.

It's very useful but it hits performance issue if your site is very high traffic.

csrf_token_generator

You can change the csrf token generation algorithm.
