## 説明

Harden your web applications.

HTTP header fields are components of the header section of request and response 
messages. The headers define the operating parameters of an HTTP transaction.

Securing HTTP headers will improve the resilience of your web application against
many common attacks including those that are on the OWASP top 10 list.

Securing headers can also improve your SEO rank and in addition to preventing websites
from being marked as dangerous by browsers and antivirus applications.

Protect sensitive user information and be compliant with privacy regulations. Defend
users from stealing private data by protecting website cookies. Use the proper directive
such as “secure”, “httponly” and “samesite”, all of those will be applied automatically
by “Secure HTTP Headers” plugin.

Secure HTTP Headers will automatically analyze any website and will build up secure
headers directives, by the latest best practice.

In addition, Secure HTTP Headers offers fully configurable options, apply or skip
any header directive as needed.

Install and activate Secure HTTP Headers with full confidence, the deactivation 
of this plugin will return your website header directives to their original state.

### 󠀁[Conflict with other Security Plugin](https://wordpress.org/support/topic/conflict-with-other-security-plugin/)󠁿

 [Mike Padua](https://profiles.wordpress.org/jsuria/) 2021年6月11日

This plugin has not been thoroughly tested. It caused a code 500 error on our Wordpress
installation (good thing it was just staging!), making the site and admin panel 
inaccessible. Please pull this out of the plugin market as this needs to be tested
alongside different security plugins as well.

Thank you for developing this plugin. Combined with another plugin, the default 
configuration is helping to get the ‘A’ rating I was looking for from the url test.
