Implementation of Connector in Tomcat

In Apache Tomcat, a connector is a key component that handles communication with clients, including receiving requests and sending responses. Tomcat supports a variety of connectors, including HTTP, HTTPS and AJP (Apache JServ Protocol). Each connector can be configured with different ports, protocols, and other parameters to meet specific deployment needs.

Basic configuration of connectors

Connectors are usually found in Tomcatconf/Configuration in the file. Here is an example of a basic HTTP connector configuration:

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           redirectPort="8443" />
  • port: Specify the port number that the connector listens for.
  • protocol: Specify the protocol used, such asHTTP/1.1。
  • connectionTimeout: Specifies the connection timeout (in milliseconds), that is, the time the server is waiting for the client to send a request.
  • redirectPort: If a request is received that requires SSL encryption and the connector itself does not support SSL, the request is redirected to this port.

Configure HTTPS connector

To configure the HTTPS connector, you need to specify SSL-related parameters such as port, protocol, and certificate information. Here is an example configuration of an HTTPS connector:

<Connector port="8443" protocol=".http11.Http11Protocol"
           maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
           clientAuth="false" sslProtocol="TLS"
           keystoreFile="path/to/" keystorePass="password" />
  • maxThreads: Specifies the maximum number of threads the connector can create to handle requests.
  • SSLEnabled: Set totrueto enable SSL.
  • scheme: Set tohttps。
  • secure: Set totrue。
  • clientAuth: If client certificate verification is required, set totrue。
  • sslProtocol: Specify the SSL protocol, such asTLS。
  • keystoreFile: Specify the path to the keystore file containing the SSL certificate.
  • keystorePass: Specify the password for the keystore.

Configuring the AJP connector

AJP connectors are commonly used to integrate with Apache HTTP servers to receive requests from Apache through the AJP protocol. Here is an example configuration of an AJP connector:

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
  • port: Specify the port number that the AJP connector listens for.
  • protocol: Specify the protocol used, such asAJP/1.3。
  • redirectPort: Same as in HTTP connectors for redirecting to SSL ports.

Summarize

Connectors are the key components in Tomcat that handle client connections and requests. ByDifferent types of connectors are configured in it, such as HTTP, HTTPS and AJP, and you can adjust Tomcat's network communication behavior as needed. Properly configuring the connector is essential to ensure efficient operation and security of the Tomcat server. With the above example, you can adjust the configuration of the connector according to your needs to optimize performance and security.
