  • All Implemented Interfaces:
    com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, AlternateProtocolsCacheOptionsOrBuilder, java.io.Serializable

    public final class AlternateProtocolsCacheOptions
    extends com.google.protobuf.GeneratedMessage
    implements AlternateProtocolsCacheOptionsOrBuilder
     Configures the alternate protocols cache which tracks alternate protocols that can be used to
     make an HTTP connection to an origin server. See https://tools.ietf.org/html/rfc7838 for
     HTTP Alternative Services and https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-svcb-https-04
     for the "HTTPS" DNS resource record.

      • getName

        public java.lang.String getName()
         The name of the cache. Multiple named caches allow independent alternate protocols cache
         configurations to operate within a single Envoy process using different configurations. All
         alternate protocols cache options with the same name *must* be equal in all fields when
         referenced from different configuration components. Configuration will fail to load if this is
         not the case.

      • hasMaxEntries

        public boolean hasMaxEntries()
         The maximum number of entries that the cache will hold. If not specified defaults to 1024.
        
         .. note:
        
         The implementation is approximate and enforced independently on each worker thread, thus
         it is possible for the maximum entries in the cache to go slightly above the configured
         value depending on timing. This is similar to how other circuit breakers work.

        Specified by:

        Returns:

      • getCanonicalSuffixesList

        public com.google.protobuf.ProtocolStringList getCanonicalSuffixesList()
         Optional list of hostnames suffixes for which Alt-Svc entries can be shared. For example, if
         this list contained the value ``.c.example.com``, then an Alt-Svc entry for ``foo.c.example.com``
         could be shared with ``bar.c.example.com`` but would not be shared with ``baz.example.com``. On
         the other hand, if the list contained the value ``.example.com`` then all three hosts could share
         Alt-Svc entries. Each entry must start with ``.``. If a hostname matches multiple suffixes, the
         first listed suffix will be used.
        
         Since lookup in this list is O(n), it is recommended that the number of suffixes be limited.
