Stanford University Libraries assists in the publication of PsychiatryOnline Journals.APPI accepts no responsibility for claims made by advertisers.Connector component that communicates with a web
connector via the AJP protocol.Route attribute of the
Engine.The native connectors supported with this Tomcat release are:
JK 1.Other native connectors supporting AJP may work, but are no longer supported.DNS lookup and return the IP
address in String form instead (thereby improving performance).By default, DNS lookups are enabled.SSL handshake and the buffer emptied when the request
is processed.Setting the attribute to zero will disable the saving of
POST data during authentication.See Proxy Support for more
information.See Proxy Support for more
information.This attribute controls request registration for JMX monitoring
of the Connector.It is enabled by default, but may be turned
it off to save a bit of memory.Set this attribute to the name of the protocol you wish to have
returned by calls to request.The default value is "http".Set this attribute to true if you wish to have
calls to request.Connector (you would want this on an
SSL Connector).This specifies if the encoding specified in contentType should be used
for URI query parameters, instead of using the URIEncoding.Type, or explicitely set using
Request.The default value is false.To use AJP, you
must specify the protocol attribute (see above).This implementation supports the AJP 1.Connector will only listen on the loopback
interface.The maximum queue length for incoming connection requests when
all possible request processing threads are in use.The default value is infinite (i.The minimum number of processors to start at initialization time.If not specified, this atttribute is set to 5.For example, if the web server is Apache 1.Processors value of zero (0) signifies that
the number of processors is unlimited.The number of request processing threads that will be created
when this Connector is first started.Normally it is not necessary to change
the maximum packet size.Problems with the default value have been
reported when sending certificates or certificate chains.The TCP port number on which this Connector
will create a server socket and await incoming connections.This is set to false by
default.If set to true, then a random value for
request.It is for use with
request.Otherwise, the authenticated principal will be propagated from the native
webserver and used for authorization in Tomcat.The default value is true.Where I was able, I've
offered some possible justifications for certain choices, but those are
only my guesses.In general, the C code which Shachor wrote is very clean
and comprehensible (if almost totally undocumented).I've cleaned up the
Java code, and I think it's reasonably readable.Scheme() will function correctly within the servlet
container.The client certificates and cipher suite will be
available to servlets as request attributes.The web server communicates with the servlet container over
TCP connections.Once a connection is assigned to handle a particular request, the basic
request informaton (e.At this point, the servlet container is presumably ready to start
processing the request.SEND_HEADERS Send a set of headers back to the browser.Each message is accompanied by a differently formatted packet of data.There are four data types in the protocol: bytes, booleans, integers and
strings.Java side, which is littered with odd autoincrement
statements to skip over these terminators.The actual length of the packet is encoded in the
header.The web server asks the container to shut itself down.The web server asks the container to take control (secure login phase).The web server asks the container to respond quickly with a CPong.To ensure some
basic security, the container will only actually do the Shutdown if the
request comes from the same machine on which it's hosted.The first Data packet is send immediatly after the Forward Request by the web server.Send the response headers from the servlet container to the web
server (and presumably, onto the browser).See above for details on other prefix codes.The structure of request_headers is the following:
First, the number of headers num_headers is encoded.POST request, for example), and immediately
reads a separate packet off the input stream to get that body.AName (the name of the attribut follows)
?Beyond this list of basic attributes, any number of other attributes can
be sent via the req_attribute code (0x0A).This signals both the end of the list of attributes and
also then end of the Request Packet.The chunk is basically binary data, and is sent directly back to the browser.The response header names are encoded the same way the request header names are.See above for details about how the the
codes are distinguished from the strings.After the code or the string header name, the header value is immediately
encoded.TCP connection can now be used to
handle new incoming requests.If there is no more data in the body (i.There is no
provision to send a second packet of request headers in case there are more
than 8K (I think this is correctly handled for response headers, though I'm
not certain).I'll bet there is
(combine long cookies with long ssl information and a lot of environment
variables, and you should hit 8K easily).There doesn't seem to be any authentication
of the connection between the web server and the container.This strikes
me as potentially dangerous.The Apache JServe Protocol (AJP) is a binary protocol that can conduit inbound requests from a web server through to an application server that sits behind the web server.It also supports some monitoring in terms of the web server being able to ping the application server.AJP is implemented in Apache HTTP Server 1.The Apache server is written in C and the application server end is generally written in Java.Application server AJP support is provided in the Apache Tomcat servlet container as well as the Jetty servlet container.Support for the WebObjects application server can be achieved (without a servlet deployment) using the LEWOAJPAdaptor from LEWOStuff.All text is available under the terms of the GNU Free Documentation License.The American Society for Investigative Pathology publishes American Journal of Pathology.
