User-Agent: Mozilla5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko20100316 Firefox3.6.2.

The following works in my program (compliance is Java 1.8):URL clSourceUrl new URL(clSource); URLConnection urlConn clSourceUrl.openConnection(); urlConn.setRequestProperty(User-Agent,Mozilla5.0 (Windows NT 6.1; Win64; x64; rv:56.0) Gecko20100101 Firefox56.0); Can you elaborate, please.

Im using Java 1.8.0 r172, so the most recent release of Java 8.

Apparently you can also just use a URLConnection, as shown in my previous comment.

If you are able to leverage such libraries, I strongly encourage you to do so.

For the examples shown here, I used Java 10 ( 10.0.2 ).

Running the examples with older Java versions may result in errors when making requests through a proxy that requires NTLM authentication ( see exception at the bottom of this post ).

It allows calling classes to obtain configured java.net.Proxy instances.

That is, this class returns a configured java.net.Proxy object.

Most importantly, note that setting a CookieHandler as shown in line 28 is needed to support the NTLM proxy authentication process.

It is named ProxyAuthenticator and extends java.net.Authenticator for this purpose.

This class is used to pass authentication credentials, namely username and password, to proxies that require them.

I used Eclipse 2018-12 (4.10.0).

The response, in this case JSON text, will be printed to the console as shown below.

If you need to run the same request through a proxy that also requires authentication, you can change the existing example to use the ProxyAuthenticator and ProxyFactory classes.

Provide the domain name, user name and password as shown in line 20, if required.

In my case, I am using a NTLM proxy that requires authentication.

For details on the NTLM authentication process, refer to this Microsoft NTLM article.

The console output shows that the getPasswordAuthentication of ProxyAuthenticator is invoked during the NTLM authentication process.

Older Java versions such as Java 8 may result in the below exception that is caused by a NTLM authentication failure.

For more details on this issue have a look at the given links.

It simply handles POST requests and prints the payload data to the console.

The Servlet simply prints the data that it receives from the client.
