Does this help (in the application class)? From some ancient code I wrote:
public WOResponse dispatchRequest(WORequest aRequest) {
try {
String uri = aRequest.uri();
String appURLPrefix = aRequest.applicationURLPrefix();
String reqHandlerKey = aRequest.requestHandlerKey();
if ( uri.startsWith(appURLPrefix+"/"+reqHandlerKey+"/") &&
(uri.endsWith(".gif") || uri.endsWith(".jpg")
|| uri.endsWith(".png")) ) {
WOResponse imageReplacement = new WOResponse();
imageReplacement.setStatus(WOResponse.HTTP_STATUS_NOT_FOUND);
imageReplacement.disableClientCaching();
return imageReplacement;
}
} catch (Exception e) {
NSLog.err.appendln("Error while checking request for images we
don't handle. User likely lost the session.");
}
return super.dispatchRequest(aRequest);
}
