What is a Tomcat worker?
A Tomcat worker is a Tomcat instance that is waiting to execute servlets or any other content on behalf of some web server. For example, we can have a web server such as the Apache HTTP Server forwarding servlet requests to a Tomcat process (the worker) running behind it.
What is ajp12?
The ajp12 typed workers forward requests to out-of-process Tomcat workers using the ajp12 protocol over TCP/IP sockets. It does not use persistent connections. The ajp12 worker properties are: host property sets the host where the Tomcat worker is listening for ajp12 requests.
Can Tomcat do load balancing?
Load balancing improves the distribution of workloads across multiple Tomcat servers. Load balancing aims to optimize resource use, maximize throughput, minimize response time, and avoid overload of any single resource.
What is HttpPlatformHandler?
HttpPlatformHandler is an Internet Information Services (IIS) module that you can use to: Manage any process (such as Tomcat, Jetty, node.exe, and Ruby) that can listen on a port for HTTP requests. Send proxy requests to the process that it manages.
What are workers in Apache?
Worker MPM. Apache HTTPD web server comes with three Multi-Processing Modules (MPM) – Prefork, Worker, and Event. The MPMs are responsible for binding to network ports on the machine, accepting requests, and dispatching children to handle the requests.
How many requests can Tomcat handle?
The default installation of Tomcat sets the maximum number of HTTP servicing threads at 200. Effectively, this means that the system can handle a maximum of 200 simultaneous HTTP requests.
What is the use of mod_jk?
The mod_jk connector is an Apache HTTPD module that allows HTTPD to communicate with Apache Tomcat instances over the AJP protocol. The module is used in conjunction with Tomcat’s AJP Connector component.
What is jvmRoute in Tomcat?
jvmRoute. A routing identifier for this Tomcat instance. It will be added to the session id to allow for stateless stickyness routing by load balancers. The details on how the jvmRoute will be included in the id are implementation dependent. See Standard Implementation for the default behavior.
What is Tomcat AJP?
Apache JServ Protocol, or AJP, is an optimized binary version of HTTP that is typically used to allow Tomcat to communicate with an Apache web server.
How configure Tomcat in IIS?

What is the difference between mod_jk and mod_cluster?
Like mod_jk and mod_proxy, mod_cluster uses a communication channel to forward requests from the load balancer to one of a set of application server nodes. Unlike mod_jk and mod_proxy, mod_cluster leverages an additional connection between the application server nodes and the load balancer.
What is mod_jk module?
What is the difference between JNI workers and connection directives?
JNI workers are no longer supported and will likely not work. Do not use them. Connection directives defines the parameters needed to connect and maintain the connections pool of persistent connections between JK and remote Tomcat. Host name or IP address of the backend Tomcat instance. The remote Tomcat must support the AJP13 protocol stack.
Do template workers have to contain mandatory directives?
Such a template worker does not have to contain mandatory directives. This approach is especially useful, if one has a lot of balanced workers in a load balancer and these workers share most of their properties.
How to secure status workers on public sites?
Make sure to secure that path with IP or some other means before placing the status worker on any public site. In a default install you will find the workers.properties and uriworkermap.properties file in your c:ColdFusion2016configwsconfig1 directory.
