No problem, I completely understand your position :-)

I understand that you have a particular application in mind and have found that apache doesn't
easily support it. So from your POV, that's obviously a limitation. All the same, I've been
on this list for a few years and you're the first person to ask this question so I wouldn't
say people are exactly clamouring for it...

Whenever you run up against a brick wall like this, it's always worth checking if you're really
going the right way. I guess that you have a large directory hierarchy and you want to use
apache as a file-system browser. But, you want to mask certain files in certain directories
on a fairly ad hoc basis. As we see, you can't switch on and off IndexIgnore on a per-directory
basis so maybe you have to think about the directory structure and/or the filenaming conventions?


For example, AFAIK, IndexIgnore is additive going *down* the hierarchy but resets itself going
*across* the filesystem, eg:

/dir1
  IndexIgnore .abc
  /dir1/subdir1
    IndexIgnore .def
	--> .abc and .def ignored in /dir1/subdir1
/dir2
  IndexIgnore .uvw
  /dir1/subdir2
    IndexIgnore .xyz
	--> .uvw and .xyz ignored in /dir2/subdir2

So maybe by re-arranging your files, you can get the result you want?

It sounds a bit like you think that the main reason apache was invented was to allow filesystem
browsing :-)

In fact, this functionality is almost a bonus feature... I guess the ignore feature was added
in emulation of the similar feature in CVS, and that's additive too :-(

BTW, I wouldn't really call it a restriction - rather, you desire a functionality that isn't
present. Apache can't make tea either, but I wouldn't say it has a no-tea-making restriction...

Rgds,
