<para> If you use an <literal><http></literal> element within your application, a
|
||||
<classname>FilterChainProxy</classname> bean named "springSecurityFilterChain" is
|
||||
created and the configuration within the element is used to build a filter chain within
|

<classname>FilterChainProxy</classname>. As of Spring Security 3.1, additional

<literal>http</literal> elements can be used to add extra filter chains <footnote>

for the web layer of your application. It creates a

maintains the stack of security filters which make up the web security configuration <footnote>

up the mapping from your <literal>web.xml</literal></para>

|

added to the stack depending on the attributes and child elements which are present. The

positions of the standard filters are fixed (see <link xlink:href="#filter-stack">the
