Embedded Jetty Container
The following settings and properties are available from the CAS configuration catalog:
cas.server.jetty.sni-host-checkServer Name Indication is an extension of the Transport Layer Security (TLS) protocol, which allows a client to indicate which hostname it is attempting to connect to at the start of the handshaking process.
trueServer Name Indication is an extension of the Transport Layer Security (TLS) protocol, which allows a client to indicate which hostname it is attempting to connect to at the start of the handshaking process. This is particularly useful when a server hosts multiple domains with different SSL certificates on a single IP address. Setting this setting to false would mean that the Jetty server will not strictly require clients to send an SNI extension during the SSL/TLS handshake and disables host name checking for Server Name Indication (SNI) during SSL/TLS handshakes.
server.jetty.accesslog.appendAppend to log.
falseAppend to log.
server.jetty.accesslog.custom-formatCustom log format, see org.eclipse.jetty.server.CustomRequestLog.
Custom log format, see org.eclipse.jetty.server.CustomRequestLog. If defined, overrides the "format" configuration key.
server.jetty.accesslog.date-format
server.jetty.accesslog.enabledEnable access log.
falseEnable access log.
server.jetty.accesslog.extended-format
server.jetty.accesslog.file-date-formatDate format to place in log file name.
Date format to place in log file name.
server.jetty.accesslog.filenameLog filename.
Log filename. If not specified, logs redirect to "System.err".
server.jetty.accesslog.formatLog format.
Log format.
server.jetty.accesslog.ignore-pathsRequest paths that should not be logged.
Request paths that should not be logged.
server.jetty.accesslog.locale
server.jetty.accesslog.log-cookies
server.jetty.accesslog.log-latency
server.jetty.accesslog.log-server
server.jetty.accesslog.retention-periodNumber of days before rotated log files are deleted.
31Number of days before rotated log files are deleted.
server.jetty.accesslog.time-zone
server.jetty.connection-idle-timeoutTime that the connection can be idle before it is closed.
Time that the connection can be idle before it is closed.
server.jetty.forwarded-headers.header-formatFormat of the forwarded headers to support.
x-forwardedFormat of the forwarded headers to support.
server.jetty.max-connectionsMaximum number of connections that the server accepts and processes at any given time.
-1Maximum number of connections that the server accepts and processes at any given time.
server.jetty.max-form-keysMaximum number of form keys.
1000Maximum number of form keys.
server.jetty.max-http-form-post-sizeMaximum size of the form content in any HTTP post request.
200000BMaximum size of the form content in any HTTP post request.
server.jetty.max-http-post-size
server.jetty.max-http-response-header-sizeMaximum size of the HTTP response header.
16KBMaximum size of the HTTP response header.
server.jetty.threads.acceptorsNumber of acceptor threads to use.
-1Number of acceptor threads to use. When the value is -1, the default, the number of acceptors is derived from the operating environment.
server.jetty.threads.idle-timeoutMaximum thread idle time.
60000msMaximum thread idle time.
server.jetty.threads.maxMaximum number of threads.
200Maximum number of threads.
server.jetty.threads.max-queue-capacityMaximum capacity of the thread pool's backing queue.
Maximum capacity of the thread pool's backing queue. A default is computed based on the threading configuration.
server.jetty.threads.minMinimum number of threads.
8Minimum number of threads. Doesn't have an effect if virtual threads are enabled.
server.jetty.threads.selectorsNumber of selector threads to use.
-1Number of selector threads to use. When the value is -1, the default, the number of selectors is derived from the operating environment.
Required settings may be needed to activate or affect the feature; review them even when they have a default. Optional settings only need to be set to change a default or to turn on the behavior they control. Third party settings belong to libraries such as Spring Boot that CAS builds on; their own documentation may have more detail.
Notes on configuration
Configuration Metadata
The collection of configuration properties listed in this section are automatically generated from the CAS source and components that contain the actual field definitions, types, descriptions, modules, etc. This metadata may not always be 100% accurate, or could be lacking details and sufficient explanations.
Be Selective
This section is meant as a guide only. Do NOT copy/paste the entire collection of settings into your CAS configuration; rather pick only the properties that you need. Do NOT enable settings unless you are certain of their purpose and do NOT copy settings into your configuration only to keep them as reference. All these ideas lead to upgrade headaches, maintenance nightmares and premature aging.
YAGNI
Note that for nearly ALL use cases, declaring and configuring properties listed here is sufficient. You should NOT have to explicitly massage a CAS XML/Java/etc configuration file to design an authentication handler, create attribute release policies, etc. CAS at runtime will auto-configure all required changes for you. If you are unsure about the meaning of a given CAS setting, do NOT turn it on without hesitation. Review the codebase or better yet, ask questions to clarify the intended behavior.
Naming Convention
Property names can be specified in very relaxed terms. For instance cas.someProperty, cas.some-property, cas.some_property are all valid names. While all
forms are accepted by CAS, there are certain components (in CAS and other frameworks used) whose activation at runtime is conditional on a property value, where
this property is required to have been specified in CAS configuration using kebab case. This is both true for properties that are owned by CAS as well as those
that might be presented to the system via an external library or framework such as Spring Boot, etc.
Note
When possible, properties should be stored in lower-case kebab format, such as cas.property-name=value.
The only possible exception to this rule is when naming actuator endpoints; The name of the
actuator endpoints (i.e. ssoSessions) MUST remain in camelCase mode.
Settings and properties that are controlled by the CAS platform directly always begin with the prefix cas. All other settings are controlled and provided
to CAS via other underlying frameworks and may have their own schemas and syntax. BE CAREFUL with
the distinction. Unrecognized properties are rejected by CAS and/or frameworks upon which CAS depends. This means if you somehow misspell a property definition
or fail to adhere to the dot-notation syntax and such, your setting is entirely refused by CAS and likely the feature it controls will never be activated in the
way you intend.
Validation
Configuration properties are automatically validated on CAS startup to report issues with configuration binding, especially if defined CAS settings cannot be recognized or validated by the configuration schema. Additional validation processes are also handled via Configuration Metadata and property migrations applied automatically on startup by Spring Boot and family.
Indexed Settings
CAS settings able to accept multiple values are typically documented with an index, such as cas.some.setting[0]=value. The index [0] is meant to be
incremented by the adopter to allow for distinct multiple configuration blocks.
