expose Tomcat internals may be explicitly requested by name but are often
deliberately not included when requesting a list of available attributes.</p>

suite being used on an SSL connection.</p>

<p>The Servlet specification defined attribute for the key size being used
on an SSL connection.</p>
</property>
<property name="jakarta.servlet.request.secure_protocol">

security protocol (e.g. TLSv1.3) being used on a secured connection.</p>

X509Certificate objects representing the certificate chain presented by
our client, if any.</p>
</property>
<property name="org.apache.catalina.ASYNC_SUPPORTED">
<p>Does the processing chain (Servlet, Filters, Valves) for the current
request support asynchronous processing? Each component in the chain must
support asynchronous processing for this to be <code>true</code>.</p>
</property>
<property name="org.apache.catalina.NAMED">
<p>The name of the target Servlet for the current named dispatch, if
any.</p>
</property>

request.</p>
</property>
<property name="org.apache.catalina.core.DISPATCHER_REQUEST_PATH">
<p>The current path (Servlet Info + Path Info) to which the request has
been dispatched.</p>
</property>
<property name="org.apache.catalina.filters.RemoteIpFilter.secure">
<p>The request attribute that is set to the value of
<code>Boolean.TRUE</code> if the RemoteIpFilter determines that this
request was submitted via a secure channel.</p>
</property>
<property name="org.apache.catalina.realm.GSS_CREDENTIAL">
<p>The GSS credential for the currently authenticated user if they have
successfully authenticated using SPNEGO authentication.</p>
</property>
<property name="org.apache.tomcat.peerAddr">
<p>The request attribute set by the RemoteIpFilter, RemoteIpValve (and may
be set by other similar components) that identifies the connection peer IP
address.</p>
</property>
<property name="org.apache.tomcat.remoteAddr">
<p>The request attribute set by the RemoteIpFilter, RemoteIpValve (and may
be set by other similar components) that identifies for the connector the
remote IP address claimed to be associated with this request when a
request is received via one or more proxies. It is typically provided via
the X-Forwarded-For HTTP header.</p>
</property>
<property name="org.apache.tomcat.request.forwarded">
<p>The request attribute that is set to the value of
<code>Boolean.TRUE</code> by the RemoteIpFilter, RemoteIpValve (and other
similar components) that identifies a request which been forwarded via one
or more proxies.</p>
</property>
<property name="org.apache.tomcat.sendfile.end">
<p>The request attribute that can be used by a servlet to pass to the
connector the end offset (not included) of the part of a file that is to
be served by sendfile. The value should be <code>Long</code>. To serve the
complete file the value should be equal to the length of the file.</p>
</property>

</section>
<section name="ServletContext attributes">
<p>ServletContext attributes are made available to web applications via a call
to <code>ServletContext.getAttribute(String)</code>.</p>
<properties>
<property name="org.apache.catalina.CredentialHandler">
