public interface AssetRequestHandler
Asset to
the user agent (i.e., the client web browser). When contributed to the AssetDispatcher service,
the contributed key is a handler id (such as "meta/core").
An example request path might be /assets/meta/core/dd8d73ac51dbab28caaec4865d302bf2/deselect.png.
The handler id would be
meta/core, the checksum of the resource content is the
hex string, and the extra path would be select.png.AssetDispatcher,

Given a request targeted (via the handler id) to the specific handler, process the request.

boolean handleAssetRequest(Request request, Response response, String extraPath) throws IOException
Response.getOutputStream(String)) or an error response
(via Response.sendError(int, String)). It is the handler's responsibility to allow
for client-side caching (possibly sending an HttpServletResponse.SC_NOT_MODIFIED response).
The handler should return true if it provided a response. If the handler returns false, this indicates that the
extra path did not identify a known asset (virtual or otherwise) and the AssetDispatcher service should send a
HttpServletResponse.SC_NOT_FOUND response.
Starting in Tapestry 5.4, the handler is informed by the AssetRequestDispatcher
whether or not the content should be compressed (this is determined based on information in the URL).request - incoming asset requestresponse - used to send a response to clientextraPath - additional path to identify the specific assetIOException5.6.4 - Copyright © 2003-2021 The Apache Software Foundation.
