sending xml file to client

// What is the best way to send an xml file from an html web sever to a client without the client first having asked for it I think that you can't. The only way to send data to the client without he explicitly requesting it is through cookies. If 4k are enough or if you can split your data in pieces cookies seem to be OK. Just a suggestion - maybe you can achieve this with a client-side script writing the xml file to the clients hdd. But you'll face serious security restrictions because no one want's every web site to write to his hard drive. But maybe if you give write permissions to the internet gest account IUSR_ it will be possible.
