Tomcat hides the Server Name and tomcatserver

• Hide the Header ServerName in the Http request
  Method 1

  In tomcat/lib/tomcat-coyote.jar

The following two files are org/apache/coyote/http11/Constants. java and org/apache/coyote/ajp/Constants. in java, find public static final byte [] SERVER_BYTES = ByteChunk. convertToBytes ("Server: Apache-Coyote/1.1" + CRLF); then modify the red part.

Method 2 (recommended)
Modify % atat_home %/conf/server. xml

<Connector port="80" protocol="HTTP/1.1"           connectionTimeout="20000"           redirectPort="8443"            maxThreads="8192"            minSpareThreads="64"            maxSpareThreads="128"            acceptCount="128"            enableLookups="false"            server="Neo App Srv 1.0"/>

Add a row
Server = "Neo App Srv 1.0". You can define this as needed.

-Hide version numbers of error pages such as 404 and 500.
For example

The modification method is in TOMCAT_HOME/lib/catalina. jar.
