How to setup an Apache reverse proxy server example
Instead, all web-based requests should first go through a web server configured as a load balancer or a reverse proxy.To get more news about web scraping, you can visit pyproxy.com official website.
The most popular open source software used to configure a server as a reverse proxy is the Apache HTTP Server. Unfortunately, Apache is not pre-configured to pass application server requests to the backend origin servers waiting to handle them.
Install Apache and the origin servers
For this example, we assume you already have installed the Apache Web Server and the origin server.The term origin server is the technical name for any application server that handles requests passed to it by the Apache reverse proxy server. In the Java ecosystem, this is likely handled by Tomcat, Jetty, JBoss, Wildfly or WebSphere Application Server. Alternatively, any non-Java resource such as an Nginx or Express server can host Node-based applications.
Apache Tomcat app deployment
For this example, we will configure the Apache Reverse Proxy to forward requests to the Tomcat Sample war file.Apache Tomcat provides the Sample app to demonstrate how to deploy applications to the server. The Tomcat 10 version can be downloaded here.
With the Apache mod_proxy library enabled, and Apache’s ProxyPassReverse setting configured, simply restart the httpd process that supports the web server and invoke the Sample app on port 80 of the web server.The Apache reverse proxy handles the incoming request, recognizes that an Apache ProxyPassReverse setting exists, and then forwards the request to Tomcat. Then Tomcat handles the request, returns a response to the Apache reverse proxy, and Apache returns the response to the client. If the sample comes up in the client browser, the Apache ProxyPassReverse example is considered a success.
The use of a reverse proxy is a common configuration in modern enterprise architectures. The simplicity and ease to set up Apache proxy servers is a testament to the benefits of open source software and the great software provided by the Apache Software Foundation.
