Answer 1

I had the same problem while tried to redirect the apache2(running on port 80) request to tomcat(application server running on port 8080).

This is the configuration which is working perfectly.

Go to /etc/apache2/sites-available/000-default.conf and add the following config:

    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    # for redirecting the websocket requests
    ProxyPass /ws ws://localhost:7681/ 
    #ProxyPass  /ws ws://localhost:7681/

    ProxyPassReverse   /ws ws://localhost:7681/

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf


# for redirecting the http request 
   ProxyPass /applicationContextUrl                         '  http://localhost:8080/applicationContextUrl

   ProxyPassReverse /applicationContextUrl         http://localhost:8080/applicationContextUrl

   ProxyPassReverseCookiePath /applicationContextUrl / 
   ProxyPassReverseCookieDomain localhost applicationContextUrl
   ProxyRequests off
   ProxyTimeout 15


   ErrorLog ${APACHE_LOG_DIR}/nirad_error.log
   LogLevel debug
CustomLog ${APACHE_LOG_DIR}/nirad_access.log combined

       AddDefaultCharset off
       Order deny,allow
       Allow from all
       #Require all denied
       Require all granted
       Require local

Done. Now goto terminal and hit the following command.

1. sudo a2enmod proxy_http (for http redirection).
2. sudo a2enmod proxy_wstunnel (for websocket redirection)
3. and sudo service apache2 restart
4. run your application server on port 8080
