public Class SSLValve

extends ValveBase
Class Inheritance
Imports
java.io.ByteArrayInputStream, .IOException, java.nio.charset.StandardCharsets, java.security.NoSuchProviderException, java.security.cert.CertificateFactory, .X509Certificate, jakarta.servlet.ServletException, org.apache.catalina.Globals, org.apache.catalina.connector.Request, .Response, org.apache.juli.logging.Log, .LogFactory, org.apache.tomcat.util.buf.UDecoder

When using mod_proxy_http, the client SSL information is not included in the protocol (unlike mod_jk and mod_proxy_ajp). To make the client SSL information available to Tomcat, some additional configuration is required. In httpd, mod_headers is used to add the SSL information as HTTP headers. In Tomcat, this valve is used to read the information from the HTTP headers and insert it into the request.

Note

Ensure that the headers are always set by httpd for all requests to prevent a client spoofing SSL information by sending fake headers.

In httpd.conf add the following:

<IfModule ssl_module>
  RequestHeader set SSL_CLIENT_CERT "%{SSL_CLIENT_CERT}s"
  RequestHeader set SSL_CIPHER "%{SSL_CIPHER}s"
  RequestHeader set SSL_SESSION_ID "%{SSL_SESSION_ID}s"
  RequestHeader set SSL_CIPHER_USEKEYSIZE "%{SSL_CIPHER_USEKEYSIZE}s"
</IfModule>
In server.xml, configure this valve under the Engine element in server.xml:
<Engine ...>
  <Valve className="org.apache.catalina.valves.SSLValve" />
  <Host ... />
</Engine>

Doc from org.apache.catalina.Valve.invoke.

Perform request processing as required by this Valve.

An individual Valve MAY perform the following actions, in the specified order:

  • Examine and/or modify the properties of the specified Request and Response.
  • Examine the properties of the specified Request, completely generate the corresponding Response, and return control to the caller.
  • Examine the properties of the specified Request and Response, wrap either or both of these objects to supplement their functionality, and pass them on.
  • If the corresponding Response was not generated (and control was not returned, call the next Valve in the pipeline (if there is one) by executing getNext().invoke().
  • Examine, but not modify, the properties of the resulting Response (which was created by a subsequently invoked Valve or Container).

A Valve MUST NOT do any of the following things:

  • Change request properties that have already been used to direct the flow of processing control for this request (for instance, trying to change the virtual host to which a Request should be sent from a pipeline attached to a Host or Context in the standard implementation).
  • Create a completed Response AND pass this Request and Response on to the next Valve in the pipeline.
  • Consume bytes from the input stream associated with the Request, unless it is completely generating the response, or wrapping the request before passing it on.
  • Modify the HTTP headers included with the Response after the getNext().invoke() method has returned.
  • Perform any actions on the output stream associated with the specified Response after the getNext().invoke() method has returned.
Parameters
request:Request

The servlet request to be processed

response:Response

The servlet response to be created

Exceptions
IOException:
if an input/output error occurs, or is thrown by a subsequently invoked Valve, Filter, or Servlet
