A web server in a server network with a centralized administrative and/or content (CAC) server executes a modified "404: Not Found" Handler. When a requested file is present within the web server's temporary storage, the file is retrieved from the temporary directory and provided in response to the request from the requesting client (browser). Also, the web server automatically initiates retrieval of a more current copy of the file from the CAC server. However, when the requested file is not present within the server's temporary directory, the modified handler checks whether the requested file is available for download from the CAC server and retrieves the requested file from the CAC server, rather than issuing the standard 404: Not Found error response. The 404: Not Found error response is only issued when the requested file is not available at both the temporary directory and the CAC server. |
