NAME
Apache::WinBitHack - An Apache module to emulate XBitHack on Win32
SYNOPSIS
In Apache's httpd.conf:
PerlModule Apache::WinBitHack
SetHandler perl-script
PerlFixupHandler Apache::WinBitHack
XBitHack Full
Options MultiViews Indexes Includes
DESCRIPTION
Apache contains a very useful directive 'XBitHack', whereby a file that
has the user-execute bit set will be treated as a server-parsed html
document. As well, the group-execute bit can be used to set the
Last-modified time of the returned file to be the last modified time of
the file, which is useful in determining if a document is to be cached
or not. On Win32 the directive works in principle, but in an
inconvenient fashion - the execute bit is set on Win32 by the file
extension, which means that documents that are to take advantage of
'XBitHack' must have an extension like 'exe' or 'bat'.
This module emulates 'XBitHack' on Win32 by, rather than using the user
and group execute bits, using instead the attributes of the file to
determine if the file is to be server-parsed by mod_include. Attributes
of a file on Win32, which you can see by running
C:\> attrib file_name
include 'archive', 'hidden', 'read-only', and 'system'. Normal user
files have just the 'archive' attribute set, which some back-up programs
use to determine if the file should be included in the next incremental
backup (most backup programs now instead use the last-modified-time of
the file for this purpose). By setting certain attributes of the file
and specifying directives as in the SYNOPSIS, particularly the
'Includes' option, 'XBitHack' can be emulated in the following ways.
XBitHack Off
With this directive, no server-side parsing of the file will be
performed.
XBitHack On
This directive emulates setting the user-execute bit. With this
directive, a file will parsed by mod_include if the 'archive' attribute
is unset, which you can do by
C:\> attrib -a file_name
Note that when a user's file is first created or when it is edited the
'archive' attribute will normally be set (and all others unset), so you
must intentionally unset the 'archive' attribute to enable
server-parsing of the file.
XBitHack Full
This directive emulates the action of also setting the group-execute
bit. With this directive, as with 'XBitHack On', a file will be parsed
by mod_include if the 'archive' attribute is unset. As well, a
Last-modified header will be sent, equal to the last-modified time of
the file, *unless* the 'read-only' attribute of the file is set, which
you can do by
C:\> attrib +r file_name
