Just for clarification,I want to access the HTTPS url via proxy server and
proxy server has the basic authentication set.
In order to authenticate,"Proxy-Authorization Basic <encoded auth>" header
should be sent along with CONNECT request but which is missing.
you might have seen in last mail attached screenshot.If you are unable to
see then let me know how can I send it to you again?
So I created the POST request using the HttpPost class which is from the
HttpClient API. HttpClient doesn't generate the "Proxy-Authorization Basic
<encode_auth>" header so added the same and pass it to HttpClient to
extract it from the POST request.
request = new HttpPost(); //please refer screenshot in last mail for
details in request object
request.addHeader("Proxy-Authorization","Basic "+encodedAuth);
httpResponse = httpClientBuilder.execute(request);
