While there is no database conecctivity, i stop the request in a filter with a loop. During that time i want show the user a kind of Popup telling that Database at moment not is available. This i imagina can be done by polling from the client to the server if the request is stopped, but nothing happend. Maybe because poll is not asyncrous Ajax?
Is there any idea to bring information to the client?
2. Idea: When stopping the request, i forward to a information page, and keep original request and response object, the information page waits until the stop is finished and initiates the original request/response...
