Links Top Level Elements Connectors Containers Nested Components | | Introduction |
The AJP Connector element represents a
Connector component that communicates with a web
connector via the AJP protocol. This is used for cases
where you wish to invisibly integrate Tomcat 5 into an existing (or new)
Apache installation, and you want Apache to handle the static content
contained in the web application, and/or utilize Apache's SSL
processing.
This connector supports load balancing when used in conjunction with
the jvmRoute attribute of the
Engine.

| Attributes |
| Common Attributes |
All implementations of Connector
support the following attributes:
| Attribute | Description |
|---|
allowTrace |
A boolean value which can be used to enable or disable the TRACE
HTTP method. If not specified, this attribute is set to false.
| enableLookups |
Set to true if you want calls to
request.getRemoteHost() to perform DNS lookups in
order to return the actual host name of the remote client. Set
to false to skip the DNS lookup and return the IP
address in String form instead (thereby improving performance).
By default, DNS lookups are enabled.
| maxPostSize |
The maximum size in bytes of the POST which will be handled by
the container FORM URL parameter parsing. The feature can be disbled by
setting this attribute to a value inferior or equal to 0.
If not specified, this attribute is set to 2097152 (2 megabytes).
| redirectPort |
If this Connector is supporting non-SSL
requests, and a request is received for which a matching
<security-constraint> requires SSL transport,
Catalina will automatically redirect the request to the port
number specified here.
| scheme |
Set this attribute to the name of the protocol you wish to have
returned by calls to request.getScheme(). For
example, you would set this attribute to "https"
for an SSL Connector. The default value is "http".
| secure |
Set this attribute to true if you wish to have
calls to request.isSecure() to return true
for requests received by this Connector (you would want this on an
SSL Connector). The default value is false.
| URIEncoding |
This specifies the character encoding used to decode the URI bytes,
after %xx decoding the URL. If not specified, ISO-8859-1 will be used.
| useBodyEncodingForURI |
This specifies if the encoding specified in contentType should be used
for URI query parameters, instead of using the URIEncoding. This
setting is present for compatibility with Tomcat 4.1.x, where the
encoding specified in the contentType, or explicitely set using
Request.setCharacterEncoding method was also used for the parameters from
the URL. The default value is false.

|
| Standard Implementation |
The standard implementation of AJP Connector is
org.apache.coyote.tomcat5.CoyoteConnector, but you
must specify the protocol attribute (see below).
This implementation supports the AJP 1.3 protocol.
It supports the following additional attributes (in addition to the
common attributes listed above):
| Attribute | Description |
|---|
debug |
The debugging detail level of log messages generated by this
component, with higher numbers creating more detailed output.
If not specified, this attribute is set to zero (0).
| protocol |
This attribute value must be AJP/1.3 to use the AJP
handler.
