mod-h2 v2.0.30

• Fixed bug in handling over long response headers. When the 64 KB limit
  of nghttp2 was exceeded, the request was not reset and the client was
  left hanging, waiting for it. Now the stream is reset.
• Added new directive H2MaxHeaderBlockLen to set the limit on response
  header sizes.
• Fixed handling of Timeout vs. KeepAliveTimeout when first request on a
  connection was reset.
