AWS CRT HTTP Client

• Bugfixes

  • Honor wildcard nonProxyHosts entries in CRT-based HTTP clients (AwsCrtHttpClient, AwsCrtAsyncHttpClient, and the S3/CRT client). Previously a *.suffix wildcard or a bare * from http.nonProxyHosts/no_proxy was silently ignored, so matching hosts were routed through the proxy instead of bypassing it. Supported forms are an exact host, a *.suffix wildcard (matches the domain and its subdomains), a single * for all hosts, and CIDR ranges. Entries must not contain surrounding whitespace.

Previously an entry with a leading or trailing space was treated as part of the host name and never matched, so the host was routed through the proxy instead of bypassing it.

Apache HTTP Client

• Bugfixes

  • Trimmed surrounding whitespace from nonProxyHosts / no_proxy entries so comma- or pipe-separated values with spaces (e.g. no_proxy=a.com, *.foo.com) are honored. Previously an entry with a leading or trailing space was treated as part of the host name and never matched, so the host was routed through the proxy instead of bypassing it.

URL Connection HTTP Client

• Bugfixes

  • Trimmed surrounding whitespace from nonProxyHosts / no_proxy entries so comma- or pipe-separated values with spaces (e.g. no_proxy=a.com, *.foo.com) are honored.

  • Update Netty to 4.1.137

• Bugfixes

  • Fixed the client-side rate limiting behavior of AdaptiveRetryStrategy under throttling conditions. Previously, the computed rate limit was overly aggressive, potentially allowing a request rate much lower than what the service allows, and was unstable, varying over time even when the service's allowed throughput was constant.
  • Make individual parts retryable when an in-memory AsyncRequestBody (for example one created with AsyncRequestBody.fromBytes, fromByteBuffer, or fromString) is split, such as during an S3 multipart upload. The body in these cases is entirely in memory already so no data is copied and callers no longer need to wrap the body in BufferedSplittableAsyncRequestBody to get retries.
