title: uploading multipart file to another server
body: <p>I'm working on a spring boot / Angular 6 application, I want to upload files to a server, I followed this tutorial to upload a multipart file :" <a href="https://grokonez.com/spring-framework/spring-boot/angular-5-upload-get-multipartfile-to-from-spring-boot-server" rel="nofollow noreferrer">https://grokonez.com/spring-framework/spring-boot/angular-5-upload-get-multipartfile-to-from-spring-boot-server</a> ". The upload of the file is on a folder in the application but now I want to upload the files to another server with URL; f.e : localhost:8081/uploads : it's another server, how can I do that? </p>
