Using Secure Socket Layer, you can establish a secured connection between the client and server. It helps to safeguard sensitive information such as credit card numbers, usernames, passwords, pins, etc. You can make connections more secure by creating your own SSL context using the HttpClient library.
- Apache HttpClient Tutorial
- The Commons HttpClient project is now end of life, and is no longer being developed. It has been replaced by the Apache HttpComponents project in its HttpClient and HttpCore modules, which offer better performance and more flexibility.
- Introduction HttpClient provides full support for HTTP over Secure Sockets Layer (SSL) or IETF Transport Layer Security (TLS) protocols by leveraging the Java Secure Socket Extension (JSSE). JSSE has been integrated into the Java 2 platform as of version 1.4 and works with HttpClient out of the box.
- Upon further investigation, our request client has a socket timeout of 30 seconds, whereas the socket created by the SSLConnectionSocketFactory has a request timeout of 0.

In this chapter, we will learn how to create a HttpRequest authenticated using username and password and tunnel it through a proxy to a target host, using an example.
Step 1 - Create a CredentialsProvider object
The CredentialsProvider Interface maintains a collection to hold the user login credentials. You can create its object by instantiating the BasicCredentialsProvider class, the default implementation of this interface.
Apache Httpclient Ssl Example
Step 2 - Set the credentials
You can set the required credentials to the CredentialsProvider object using the setCredentials() method. This method accepts two objects −
AuthScope object − Authentication scope specifying the details like hostname, port number, and authentication scheme name.
Credentials object − Specifying the credentials (username, password). Set the credentials using the setCredentials() method for both host and proxy as shown below.
Step 3 - Create an HttpClientBuilder object
Create a HttpClientBuilder using the custom() method of the HttpClients class as shown below −
Step 4 - Set the CredentialsProvider
You can set the CredentialsProvider object to a HttpClientBuilder object using the setDefaultCredentialsProvider() method. Pass the previously created CredentialsProvider object to this method. Sophos on vimeo.
Step 5 - Build the CloseableHttpClient
Build the CloseableHttpClient object using the build() method.

Step 6 - Create the proxy and target hosts
Create the target and proxy hosts by instantiating the HttpHost class.
Step 7 - Set the proxy and build a RequestConfig object
Apache Httpclient Ssl Data
Create a RequestConfig.Builder object using the custom() method. Set the previously created proxyHost object to the RequestConfig.Builder using the setProxy() method. Finally, build the RequestConfig object using the build() method.
Step 8 - Create a HttpGet request object and set config object to it.
Create a HttpGet object by instantiating the HttpGet class. Set the config object created in the previous step to this object using the setConfig() method.
Step 9 - Execute the request
Execute the request by passing the HttpHost object (target) and request (HttpGet) as parameters to the execute() method.
Example
Following example demonstrates how to execute a HTTP request through a proxy using username and password.
Output
On executing, the above program generates the following output −
Introduction
The Hyper-Text Transfer Protocol (HTTP) is perhaps the most significant protocol used on the Internet today. Web services, network-enabled appliances and the growth of network computing continue to expand the role of the HTTP protocol beyond user-driven web browsers, while increasing the number of applications that require HTTP support.
Although the java.net package provides basic functionality for accessing resources via HTTP, it doesn't provide the full flexibility or functionality needed by many applications. The Jakarta Commons HttpClient component seeks to fill this void by providing an efficient, up-to-date, and feature-rich package implementing the client side of the most recent HTTP standards and recommendations. See the Features page for more details on standards compliance and capabilities.

Designed for extension while providing robust support for the base HTTP protocol, the HttpClient component may be of interest to anyone building HTTP-aware client applications such as web browsers, web service clients, or systems that leverage or extend the HTTP protocol for distributed communication.

There are many projects that use HttpClient to provide the core HTTP functionality. Some of these are open source with project pages you can find on the web while others are closed source that you would never see or hear about. The Apache Source License provides maximum flexibility for source and binary reuse. Please see the Applications page for projects using HttpClient.
