Apache is the most popular HTTP server which comes with access to a very wide range of powerful extensions. Apache can be configured as a proxy to redirect HTTP traffic to other servers. When Apache is configured as a reverse proxy, it receives HTTP requests from the internet, and forwards them.
Apache is a tried and tested HTTP server which comes with access to a very wide range of powerful extensions. Although it might not seem like the go-to choice in terms of running a reverse-proxy, system administrators who already depend on Apache for the available rich feature-set can also use it as a gateway to their application servers. In most cases, this will translate to removing an additional layer from their server set up or the need to use yet another tool just to redirect connections.
Configure Apache Web Server for Websockets using Reverse Proxy This article provides basic steps to configure Apache Web Server to work with Websockets. We recently created a Spring based web application that uses web sockets for live streaming of data from the Tomcat 8.x server. The directives above secures your Apache server and sets up the reverse proxy to the Tomcat server. In this example, the Tomcat server and Apache webserver are on the same machine and Tomcat is listening on the default port of 8080.
In this DigitalOcean article, we are going to see set up Apache on Ubuntu 13 and use it as a reverse-proxy to welcome incoming connections and redirect them to application server(s) running on the same network. For this purpose, we are going to use and work with the mod_proxy extension and several other related Apache modules.

Apache
Apache HTTP server does not require an introduction, since it is probably the most famous and popular web-server that exists. It is possible to run Apache very easily on many different platforms and set ups. The application comes with a lot of third party modules to handle different kind of tasks (mod_rewrite for rule-based URL rewriting) and one of them, albeit nowadays relatively neglected, is mod_proxy: The Apache Module to implement a proxy (or gateway) for servers running on the back-end.
Tip: According to some articles, Apache’s name comes from server’s “patchy” nature - i.e. it being a collection of application patches (or modules).
Note: To learn more about Apache, you can check out the Wikipedia entry on the subject - Apache HTTP Server.
Apache Working As A Reverse-Proxy Using mod_proxy
mod_proxy is the Apache module for redirecting connections (i.e. a gateway, passing them through). It is enabled for use just like any other module and configuration is pretty basic (or standard), in line with others. mod_proxy is not just a single module but a collection of them, with each bringing a new set of functionality.
Some of these modules are:
mod_proxy: The main proxy module for Apache that manages connections and redirects them.
mod_proxy_http: This module implements the proxy features for HTTP and HTTPS protocols.
mod_proxy_ftp: This module does the same but for FTP protocol.
mod_proxy_connect: This one is used for SSL tunnelling.
mod_proxy_ajp: Used for working with the AJP protocol.
mod_proxy_wstunnel: Used for working with web-sockets (i.e. WS and WSS).
mod_proxy_balancer: Used for clustering and load-balancing.
mod_cache: Used for caching.
mod_headers: Used for managing HTTP headers.
mod_deflate: Used for compression.
Note: To learn more about Apache and mod_proxy, you can check out the official Apache documentation on the subject here.
Installing Apache And mod_proxy
Note: Instructions given here are kept brief, since chances are you already have Apache installed or know how to use it. Nonetheless, by following the steps below you can get a new Ubuntu VPS running Apache in a matter of minutes.
Updating The Operating-System
Apache2 Reverse Proxy Ssl
We will begin with preparing our virtual server. We are going to first upgrade the default available components to make sure that we have everything up-to-date.
Update the software sources list and upgrade the dated applications:

Getting The Essential Build Tools
Let’s continue with getting the essential package for application building - the build-essential. This package contains tools necessary to install certain things from source.
Run the following command to install build-essential package:
Getting The Modules And Dependencies
Next, we are going to get the module and dependencies.
Run the following command to install them:
Configuring Apache To Proxy Connections
Activating The Modules
Before configuring Apache, we are going to enable the necessary modules that we will be using in this tutorial, or which might come in handy in the future.
First, let’s verify that all modules are correctly installed and ready to be activated.
Run the following command to get a list of available Apache modules:
Once you are prompted with the choice of modules you desire, you can pass the below line listing the module names:
The list of modules:
Or alternatively, you can run the following commands to enable the modules one by one:
Note: Some modules are likely to be enabled by default. Trying to enable them twice will just ensure that they are active.
Modifying The Default Configuration
In this step, we are going to see how to modify the default configuration file 000-default.conf inside /etc/apache2/sites-enabled to set up “proxying” functionality.
Run the following command to edit the default Apache virtual host using the nano text editor:
Here, we will be defining a proxy virtual host using mod_virtualhost and mod_proxy together.
Copy-and-paste the below block of configuration, amending it to suit your needs:
Press CTRL+X and confirm with Y to save and exit.
Note: To learn more about virtual host configurations, you can check out the detailed Apache manual on the subject by clicking here.
Enabling Load-Balancing
If you have multiple back-end servers, a good way to distribute the connection when proxying them is to use Apache’s load balancing features.
Start editing the virtual-host settings like the previous step, but this time using the below configuration example:
Enabling SSL Reverse-Proxy Support
If you are dealing with SSL connections and certificates, you will also need to enable a secondary virtual host with below settings.
Repeat the steps from the previous steps but using these configuration options:
Restarting Apache
Once you are happy with your configuration, you will need to restart the cloud server for the changes to go into effect.
Execute the following command to restart Apache:
And that’s it!
You can now visit your VPS and Apache shall reverse-proxy connections to your back-end application servers.
Skip to end of metadataGo to start of metadataIn this How-To guide, we will show you how to set up a reverse proxy between your Apache webserver and your Tomcat server.
Apache Reverse Proxy Https To Http
Prerequisites
For this you are going to need the following
Tomcat | http://tomcat.apache.org/ | Tomcat application server. |
Apache proxy directives can be used in two contexts - server config and virtual host. The examples below will be in the server config context as well as pertain to Apache that has been compiled with the source package from http://httpd.apache.org.
To use the apache proxy directives you need to have the following modules loaded:
Those lines above need to be put in the Apache configuration file where other LoadModule lines are set, like for example, httpd.conf.
Next, in your configuration file add:
The directives above secures your Apache server and sets up the reverse proxy to the Tomcat server. In this example, the Tomcat server and Apache webserver are on the same machine and Tomcat is listening on the default port of 8080.
You can test to see that your proxy is working by accessing http://localhost/webapps. You should see the default Tomcat homepage. Note, that /webapps in the Location block, the ProxyPass and the ReverseProxyPass lines can be whatever you want. You can use /foo if you want and you can access Tomcat with http://localhost/foo.
Note Make sure you understand the security issues involved with proxies and set up access controls for your proxy configuration.
With a default Tomcat setup, you will have broken links in the Tomcat Manager page. Learn how to fix them with mod_proxy_html.
