Interface Summary

AccessLogValve.AccessLogElement

AccessLogElement writes the partial message into the buffer.

Class Summary

AccessLogValve	Implementation of the Valve interface that generates a web server access log with the detailed line contents matching a configurable pattern.
AccessLogValve.ByteSentElement	write bytes sent, excluding HTTP headers - %b, %B
AccessLogValve.CookieElement	write a specific cookie - %{xxx}c
AccessLogValve.DateFormatCache	Cache structure for formatted timestamps based on seconds.
AccessLogValve.ElapsedTimeElement	write time taken to process the request - %D, %T
AccessLogValve.HeaderElement	write incoming headers - %{xxx}i
AccessLogValve.HttpStatusCodeElement	write HTTP status code of the response - %s
AccessLogValve.LocalAddrElement	write local IP address - %A
AccessLogValve.LocalServerNameElement	write local server name - %v
AccessLogValve.LogicalUserNameElement	write remote logical username from identd (always returns '-') - %l
AccessLogValve.MethodElement	write request method (GET, POST, etc.) - %m
AccessLogValve.QueryElement	write Query string (prepended with a '?'
AccessLogValve.RequestAttributeElement	write an attribute in the ServletRequest - %{xxx}r
AccessLogValve.RequestElement	write first line of the request (method and request URI) - %r
AccessLogValve.RequestURIElement	write requested URL path - %U
AccessLogValve.ResponseHeaderElement	write a specific response header - %{xxx}o
AccessLogValve.SessionAttributeElement	write an attribute in the HttpSession - %{xxx}s
AccessLogValve.SessionIdElement	write user session ID - %S
AccessLogValve.StringElement	write any string
AccessLogValve.ThreadNameElement	write thread name - %I
AccessLogValve.UserElement	write remote user that was authenticated (if any), else '-' - %u
CometConnectionManagerValve	Implementation of a Valve that tracks Comet connections, and closes them when the associated session expires or the webapp is reloaded.
Constants	Manifest constants for the org.apache.catalina.valves package.
Constants.AccessLog
CrawlerSessionManagerValve	Web crawlers can trigger the creation of many thousands of sessions as they crawl a site which may result in significant memory consumption.
ErrorReportValve	Implementation of a Valve that outputs HTML error pages.
ExtendedAccessLogValve	An implementation of the W3c Extended Log File Format.
ExtendedAccessLogValve.DateElement
ExtendedAccessLogValve.PatternTokenizer
ExtendedAccessLogValve.TimeElement
JDBCAccessLogValve	This Tomcat extension logs server access directly to a database, and can be used instead of the regular file-based access log implemented in AccessLogValve.
PersistentValve	Valve that implements per-request session persistence.
RemoteAddrValve	Concrete implementation of RequestFilterValve that filters based on the string representation of the remote client's IP address.
RemoteHostValve	Concrete implementation of RequestFilterValve that filters based on the remote client's host name.
RemoteIpValve	Tomcat port of mod_remoteip, this valve replaces the apparent client remote IP address and hostname for the request with the IP address list presented by a proxy or a load balancer via a request headers (e.g.
RequestFilterValve	Implementation of a Valve that performs filtering based on comparing the appropriate request property (selected based on which subclass you choose to configure into your Container's pipeline) against the regular expressions configured for this Valve.
SemaphoreValve	Implementation of a Valve that limits concurrency.
SSLValve	When using mod_proxy_http, the client SSL information is not included in the protocol (unlike mod_jk and mod_proxy_ajp).
StuckThreadDetectionValve	This valve allows to detect requests that take a long time to process, which might indicate that the thread that is processing it is stuck.
ValveBase	Convenience base class for implementations of the Valve interface.

Package org.apache.catalina.valves Description

This package contains a variety of small Valve implementations that do not warrant being packaged separately. In addition, there is a convenience base class (ValveBase) that supports the usual mechanisms for including custom Valves into the corresponding Pipeline.

Other packages that include Valves include org.apache.tomcat.logger and org.apache.tomcat.security.
