<security-constraint>
<web-resource-collection>
<url-pattern>/bg/c/portal/protected</url-pattern>
<http-method>POST</http-method>
<http-method>GET</http-method>
</web-resource-collection>
<user-data-constraint>
<transport-guarantee>...</transport-guarantee>
</user-data-constraint>
</security-constraint>
http-method, url-pattern, , - http-method.

<security-constraint>
<web-resource-collection>
