I just started using the XSendFile apache module to serve files. Except for the fact that I cannot know when a download is complete, I guess it's pretty good...
One problem though, I found out that xsend will return 0 bytes files if XSendFilePath is not set in the apache or the vhost conf
So my question is, can I detect if XSendFilePath is set or not?
With PHP I can detect if the xsend module is loaded, but it's no good to me if I am not sure it's going to work...
So more generally, is it possible to detect a specific apache/vhost directive?
