The new HTTP client [JEP-110]

In this section, we will review Java's Hypertext Transfer Protocol (HTTP) client, starting with a pre-Java 9 look and then diving into the new HTTP client that is part of the Java 9 platform. This approach is needed to support an understanding of the changes made in Java 9.

  • HTTP_BAD_METHOD
  • HTTP_BAD_REQUEST
  • HTTP_CLIENT_TIMEOUT
  • HTTP_CONFLICT
  • HTTP_CREATED
  • HTTP_ENTITY_TOO_LARGE
  • HTTP_FORBIDDEN
  • HTTP_GONE
  • HTTP_INTERNAL_ERROR
  • HTTP_LENGTH_REQUIRED
  • HTTP_MOVED_PERM
  • HTTP_MOVED_TEMP
  • HTTP_MULT_CHOICE
  • HTTP_NO_CONTENT
