Description copied from interface: AssetRequestHandler

Given a request targeted (via the handler id) to the specific handler, process the request. The handler is responsible for processing the request, sending back either a bytestream (via 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.

Specified by:

handleAssetRequest in interface AssetRequestHandler

Parameters:

request - incoming asset request

response - used to send a response to client

extraPath - additional path to identify the specific asset

Returns:

true if request handler, false if asset not found

Throws:

IOException
