What is ajp13 protocol?

What is ajp13 protocol?

The ajp13 protocol is packet-oriented. A binary format was presumably chosen over the more readable plain text for reasons of performance. The web server communicates with the servlet container over TCP connections.

How do I know if my AJP connector is enabled?

The most common way to identify whether the protocol is indeed enabled is to first locate the web server’s conf/ directory. Look for the server. xml configuration file that specifies all the default protocols and the document root directory configuration.

Is AJP protocol secure?

EDIT: AJP is not designed to be secure, if you need security, use mod_proxy_http and proxy over https, or create SSH tunnel.

What is ajp13 used for?

AJP (Apache Jserv Protocol) is basically a binary protocol that allows to reverse proxying requests from a FE Web Server to a BE Application Server, effectively propagating all the needed information to make the Req-Res flow continuing successfully.

Should I use AJP?

Should I use http, https or ajp? For most browser to server traffic, use http. If there’s a need for security in the data (or if you’re in doubt / customers may question the security), use https. If you have intensive / busy servers with bandwidth issues between them, use ajp as your linking protocol.

How do I disable AJP connector?

To disable the AJP protocol in Apache Tomcat:

1. Edit the file server.xml.
2. Search for the section,
3. Comment out the AJP protocol configuration, from:
4. Save the server.xml file.
5. Restart Apache Tomcat. Reference.

What is the AJP connector?

AJP connectors 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. This functionality is typically required in a high-traffic production situation, where Tomcat clusters are being run behind an Apache web server.

What is AJP13 used for?

How do I disable AJP protocol port?

Process

1. Open the file that controls the AJP configuration in a text editor. $CONTRAST_HOME/data/conf/server.properties.
2. Edit the the AJP settings to set enabled.ajp to false ajp.enabled=true ajp.port=8009.
3. Save the file.
4. Restart your TeamServer.

How does the AJP protocol work?

The Apache JServ Protocol (AJP) is a binary protocol that can proxy inbound requests from a web server through to an application server that sits behind the web server. In this scenario the web server functions as a reverse proxy for the application server.

Is Ajp better than HTTP?

HTTP connectors This Connector element, which supports the HTTP/1.1 protocol, represents a single Connector component listening to a specific TCP port on a given Server for connections. However, as AJP tends to handle proxying better than HTTP, this usage is not common.

Can I disable AJP?

The first option, disabling AJP, is the most secure and robust recommended solution. Protecting AJP with a secret may be less disruptive, but requires using either mod_jk or a version of httpd that supports the secret parameter.

What kind of protocol is the AJP13 protocol?

Overview of the protocol. The ajp13 protocol is packet-oriented. A binary format was presumably chosen over the more readable plain text for reasons of performance. The web server communicates with the servlet container over TCP connections.

What kind of security does AJP13 lack?

But ajp13 lacks support for: security between web server and servlet engine. Anybody can connect to an ajp13 port (no login mechanism used) You could connect, for example with telnet, and keep the remote thread up by not sending any data (no timeout in connection)

What’s the difference between AJP and Tomcat protocols?

AJP is a wire protocol. It an optimized version of the HTTP protocol to allow a standalone web server such as Apache to talk to Tomcat. Historically, Apache has been much faster than Tomcat at serving static content.

Why is AJP13 not forwarded to servlet engine?

AJP13 was designed to be small and fast and so many SSL informations present in the web-server are not forwarded to the servlet engine. We add here four negociations flags to provide more informations on client SSL data (certs), server SSL datas, crypto used, and misc datas (timeout…).
