Package com.jcabi.http.wire

Class ETagCachingWire

  • All Implemented Interfaces:
    Wire
    @Immutable
public final class ETagCachingWire
extends AbstractHeaderBasedCachingWire
    Wire that caches requests with ETags.

    This decorator can be used when you want to avoid duplicate requests to load-sensitive resources and server supports ETags, for example: 

    
    String html = new JdkRequest("http://goggle.com")
        .through(ETagCachingWire.class)
        .fetch()
        .body();

    Client will automatically detect if server uses ETags and start adding corresponding If-None-Match to outgoing requests

    Client will take response from the cache if it is present or will query resource for that.

    The class is immutable and thread-safe.

    2.0
