Summary
The AsyncHttpClient (AHC) library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. Prior to 3.0.13 and 2.16.1, the HTTP/1.1 connection-pool key excludes the authenticated principal for connection-oriented NTLM and Negotiate authentication. A pooled socket authenticated for one request can be reused by a request carrying another principal, and the server executes that later request as the first identity. Basic and Digest are not affected because they authenticate each request. This issue is fixed in versions 3.0.13 and 2.16.1.
