OK: When you request a file, the server will send some info to you, and then the file (if it exists).
Some thing like this, if the file you requested wasn't found.
HTTP/1.0 404 Not Found

This, "Content-Length: 92166", is the info you want. In this example the file was 92166 bytes.
So to get it you need to "/sockread %var" and parse %var to find the info.
e.g. if Content-Length: * iswm %var { set %file.size $gettok(%var,2,32) }
When "%var == $null" is when the actual file will begin to download, at that time you switch to "/sockread &bvar".
