Interface ETagGenerator

All Known Subinterfaces:

Http11ResponseHandler, WebDavResponseHandler

All Known Implementing Classes:

AbstractWrappingResponseHandler, CompressingResponseHandler, DefaultETagGenerator, DefaultHttp11ResponseHandler, DefaultWebDavResponseHandler, JustCopyTheUniqueIdETagGenerator, LoginResponseHandler

public interface ETagGenerator

Generates ETags, ie entity tags. Custom implementations must be injected into:

DefaultHttp11ResponseHandler DefaultWebDavPropertySource .. or whatever you're using in their place

Note that the Http11ResponseHandler interface extends this, since it response handlers logically must know how to generate etags (or that they shouldn't be generated) and it assists with wrapping to expose that functionality, without exposing the dependency directly.

HTTP/1.1 origin servers:

SHOULD send an entity tag validator unless it is not feasible to generate one. MAY send a weak entity tag instead of a strong entity tag, if performance considerations support the use of weak entity tags, or if it is infeasible to send a strong entity tag. SHOULD send a Last-Modified value if it is feasible to send one, unless the risk of a breakdown in semantic transparency that could result from using this date in an If-Modified-Since header would lead to serious problems.
