(57) ABSTRACT
An arrangement is provided for improving the response time of a device in delivering transformed documents. Upon intercepting a request, sent by a client to a server via a device, for a document, an appropriate destination form is determined. If the destination document has been cached and the cached destination document does not need to be regenerated, the device retrieves the destination document directly from the cache and delivers it to the client. Otherwise, the document in its source format is fetched from the server and transformed into the destination document prior to its delivery to the client.
