Hi Team, I am trying to do POC using the *HttpClient 4.5.5* library and want to access *HTTPS url* masked through a http *proxy server* with *basic authentication* and its failing.
The authentication proxy header should be sent as part of the connect but it is not happening. I have also added the header "*Proxy-Authorization Basic <encodedAuth>*" to *POST request *as it requires and passing request object to httpclient through execute() method. Apart from that preemptive authentication is also set. [image: image.png] But *over the network,* "*Proxy-Authorization Basic <encodedAuth>*" header is *missing*. I tried *same *scenario to access the HTTP request everything works fine. *On the fly* [No "Proxy-Authorization" header]: [image: image.png] REQUEST: CONNECT localhost:4080 HTTP/1.1 Host: 127.0.0.1:9090 User-Agent: Apache-HttpClient/4.5.5 (Java/1.8.0_191) RESPONSE: "HTTP/1.1 407 Proxy Authentication Required Server: Proxy Proxy-Authenticate: Basic realm="**** Authorization" Cache-control: no-cache Connection: Close Proxy-Connection: Close Content-Length: 0" Could you please help me on this issue? and let me know if you require any further information. -- Thanks, Kaushal.
