Scenario: I have an Apache Server(SSL enabled) and tomcat running on my machine and there is one application (app1) hosted on tomcat which is only accessible from Apache Server. You cannot access it directly from tomcat. Now you want to access app1 using multiple domains i.e. domain1.waheedtechblog.com annd domain2.waheedtechblog.com should point to the same application which is hosted on tomcat. (I want to implement different Authentication mechanism based on different domains) Solution: The above case can be achieved using NameBased VirtualHosts and SSL. First you need to uncomment following lines form ${apache}/conf/httpd.conf file LoadModule ssl_module modules/mod_ssl.so LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_ajp_module modules/mod_proxy_ajp.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule proxy_http_module modules/mod_proxy_http.so Include conf/extra/httpd-ssl.conf then goto ${apache}/conf/extra/httpd-ssl.co...

This tutorial shows how to enable SSL support for Apache Tomcat web server. Requirement *) Apache Tomcat 5.0 *) JDK 1.5 Note: if you have JDK below 1.4, you need to install Java Secure Socket Extensions (JSSE) To install and configure SSL support on Tomcat, you need to follow these simple steps. Generating the KeyStore file: *) Create a keystore file to store the server's private key and self-signed certificate by executing the following         command. *) Enter command line and change directory to your JAVA\bin folder. (Default path is: C:\Program         Files\Java\jre6\bin). *) Type “keytool –genkey –alias tomcat –keyalg RSA" and press Enter.         Where tomcat is an alias name and RSA is a key algorithm. *) Type your password for the keystore. (Default password is: changeit). In this example, I’ll use password as “password" Enter general information about this Certificate. The example is the image be...
