Simple Secure websocket backend server connection with Apache SSL Proxy

BROWSE <-----SSL connection-----> APACHE PROXY SERVER (SSL Enabled) <----Regular plain text----> TOMCAT WEB SOCKET SERVER

1. Enable following modules:
LoadModule ssl_module modules/mod_ssl
LoadModule socache_shmcb_module modules/mod_socache_shmcb.so

2. Create self-signed digital certificate for testing as follow using openssl
> openssl genrsa -out server.key 2048 (generate private key)
> openssl req -new -key server.key -out server.csr (generate CSR)
> openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt (generate self-signed certificate from CSR)

and copy the crt and key file at: C:/Apache24/conf/ folder

3. Enable the httpd-ssl.conf in the httpd.conf file as:
Include conf/extra/httpd-ssl.conf

4. Open httpd-ssl.conf file and update the following (comment Listen 443 line if starting server gives error about the port already used by 443)
SSLCertificateFile "${SRVROOT}/conf/server.crt" and
SSLCertificateKeyFile "${SRVROOT}/conf/server.key"

5. Start the server using ./httpd.exe and see if there is any issue, if no issue then access the page using https://localhost, this will launch the secure page

6. Add the Proxy in the httpd.conf file for the Tomcat as:
ProxyRequests Off
ProxyPreserveHost On
ProxyPass /test http://tomcat-host-ip:8090/test
ProxyPassReverse /test http://tomcat-host-ip:8090/test

Here Tomcat is running at 8090 port and Proxy is set up as http, i.e. from apache to tomcat, the data is passes as plain text.

7. To automatically change the http to https when user access http, add following line in the httpd.conf file just above the ProxyPass set up as:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}

and all set, run the Apache and Tomcat and access the Tomcat page from Apache as https://localhost/text. This will be Proxied to Tomcat as desired.
