In this article, we will be looking at the advanced usage of the Apache HttpClient library. We'll look at the examples of adding custom headers to HTTP requests, and we'll see how to configure the client to authorize and send requests through a proxy server. We will be using Wiremock for stubbing the HTTP server.

Apache Reverse Proxy https to http. Ask Question Asked 4 years, 1 month ago. Active 4 years, 1 month ago. Viewed 27k times 4. I've done a fair amount of browsing on here and the Internet but I can't configure my apache to reverse proxy https to http. I feel like I'm close however. Apache's proxy features are divided into several modules in addition to modproxy: modproxyhttp, modproxyftp and modproxyconnect. Thus, if you want to use one or more of the particular proxy functions, load modproxy and the appropriate module(s) into the server (either statically at compile-time or dynamically via the LoadModule directive).

A Proxy server is an intermediary server between the client and the internet. Proxy servers offer the following basic functionalities −

  • Firewall and network data filtering

  • Network connection sharing

  • Data caching

Using HttpClient library, you can send a HTTP request using a proxy. Follow the steps given below −

Step 1 - Create a HttpHost object

Reverse

Instantiate the HttpHost class of the org.apache.http package by passing a string parameter representing the name of the proxy host, (from which you need the requests to be sent) to its constructor.

In the same way, create another HttpHost object to represent the target host to which requests need to be sent.

Step 2 - Create an HttpRoutePlanner object

The HttpRoutePlanner interface computes a route to a specified host. Create an object of this interface by instantiating the DefaultProxyRoutePlanner class, an implementation of this interface. As a parameter to its constructor, pass the above created proxy host −

Step 3 - Set the route planner to a client builder

Using the custom() method of the HttpClients class, create a HttpClientBuilder object and, to this object set the route planner created above, using the setRoutePlanner() method.

Step 4 - Build the CloseableHttpClient object

Step 5 - Create a HttpGetobject

Apache Http Proxy

Create a HTTP GET request by instantiating the HttpGet class.

Step 6 - Execute the request

One of the variants of the execute() method accepts an HttpHost and HttpRequest objects and executes the request. Execute the request using this method −

Example

Apache Http Proxy Eset

Following example demonstrates how to send a HTTP request to a server via proxy. In thisexample, we are sending a HTTP GET request to google.com via localhost. We have printed the headers of the response and the body of the response.

Output

On executing, the above program generates the following output −
