How to a request to another webserver - http

I have following scenario:
The client request for web content to the web server.
But sometimes the client use data from SAP server and make an OData request to SAP server.
How to forward OData request from the client through the webserver to SAP server? Is it possible?

U can recreate the request to the SAP server in your own web server. As soon as the client triggers the request your web service triggers the sap request. The web server waits for the response from the SAP server and return this response to the client.

Dispatching grpc requests to multiple servers via Nginx

Having a grpc client and server and they are exchanging messages in grpc unary mode. I want to log all the messages the client sends to the server without changing a single line of code in both client or server. I came across to Nginx with its new graceful grpc support. Is it possible to route grpc messages from client to server via Nginx while sending a copy of them to a remote logging service? If No, please let me know if there are any other tools out there that do the same stuff.

How can a Netty Server porcess a client request using another Netty Client for Http2 Proxy Server

My requirement is if a browser sends the request to ServerBootStrap then the ServerBootStrap creates BootStrap (Client) and that client connects with a proxy server.
The problem here is to connect with Proxy Server we need to send first HTTP CONNECT method to open a tunnel from Proxy and BootStrap (Client) and then whatever request comes from Browser to Server, the server will send BootStrap(client) and all the communication should happen.
This will look like
Browser ->ServerBootStrap(Server)->BootStrap(Client)->ProxyServer(HTTP2)
Can somebody tell me how do I implement this for Http2?
How do I send Http CONNECT from a Handler for the First time while Client instantiating and If CONNECT gets 200OK from Proxy Server I will to remove Handler from channel pipeline?
Can we explicitly call any HTTP CONNECT request while adding a handler in Pipeline and getting the response to check the status?
--Can somebody answer ?

The question is about ping url when the hub location is in a different server.

How can i see http requests sent from client to Jersey Web service

As the title explains, I want to see the http requests that are sent by my android app client to my Jersey Web service.
Also, I'm using
https://github.com/kevinsawicki/http-request
class for sending the requests, but I'm not sure if they are SSL encrypted. Can I see if they are encrypted by looking at the http requests that arrive at my Web service?
If you have access to the server on which your web service is running, you can use Wireshark : https://www.wireshark.org/
This will trace and decode the tcp/ip protocol for you, and indeed show you if it's encrypted under SSL.
Assuming you own the server, and have full access, you can also install the Private Key from your server into Wireshark, and it will then show you decoded SSL traffic.
