It's that simple.
I don't think that it is. The write()'s to the actual file arn't going to occur very often because both reading from the CGI/proxy-backend is buffered as is writing the file to disk. (and they should be, or the general case would become much slower). So mtime not being recent is no-indication of death, it could easily be a trickling download. And then the same thing is going to happen to the current request, and so on and so on and you're going to end up not caching the very requests that would benefit the most from being cached. -- Colm MacCárthaigh Public Key: [EMAIL PROTECTED]
