A metafile is a file with extra header data to go with the file served—for example, you could add a Refresh header. There seems no obvious place for this material, so we will put it here, with apologies to those readers who find it rather odd.
MetaFiles [on|off] Default: off Directory
Turns metafile processing on or off on a directory basis.
MetaDir directory_name Default directory_name: .web Directory
Names the directory in which Apache is to look for metafiles. This is usually a "hidden" subdirectory of the directory where the file is held. Set to the value "." to look in the same directory.
MetaSuffix file_suffix Default file_suffix: .meta Directory
Names the suffix of the file containing metainformation.
The default values for these directives will cause a request for DOCUMENT_ROOT/mydir/fred.html to look for metainformation (supplementing the MIME header) in DOCUMENT_ROOT/mydir/fred.html.meta.
