title: Which java http client supports status code 102 Processing?
body: <p>Our company should invoke a REST-like service over HTTP that responds status code <code>102 Processing</code> for lengthy (time-consuming) operations. As I have understood, 102 Processing is not really a part of the official HTTP standard, but <a href="https://www.rfc-editor.org/rfc/rfc2518#section-10.1" rel="nofollow noreferrer">an extension for the WebDAV protocol</a>. Said that, it is not a WebDAV we try to access but a HTTP service that &quot;borrows&quot; this status code.</p>
  <p>Which java library supports this?</p>
