Class ETagCachingWire

java.lang.Object

com.jcabi.http.wire.AbstractHeaderBasedCachingWire

com.jcabi.http.wire.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
