=======

AuthName "Pictures"  #basially, the prompt users will see
AuthType Basic
AuthUserFile /home/steve/public_html/spics/.htpasswd
AuthGroupFile /dev/null
Require valid-user
=======
SERVER SIDE INCLUDE FILES (but php is this;  is this needed now?)
XBitHack on  # server will then look at all executable files in cwd for directives
	#Equivlent to making the relevant files .shtml
<!--#include argument="./.msgfile" -->  #perl-like
	If exec by server, will include file ".msgfile"
	Alternative to php
=======
ORDER cmd:
#One main point of these 'Order's is that the order in .htaccess of the
  #'Order' line, the allow lines, and the deny lines doesn't matter.
Order allow,deny
1) apply all allow rules 2) apply all deny rules; 3) deny everything else.

Order deny,allow
1) apply all deny rules 2) apply all allow rules; 3) allow everything else.

=======
INDIVIDUAL FILE BARRING.  Needn't be after AUTH etc. in .htaccess?
<FilesMatch  "^un*">   # that bars access to all files beginning 'un'
<FilesMatch  "^onename$">   # that bars access to one file with full name
order allow,deny
#deny from all #Means deny TO all users. Actually redundant, given 'order' line.
</FilesMatch>


======
Customised error docs
Can be good for offering user near-matches; redirects; auto-correct (search
for near-match and auto-jump if only one of them).

ErrorDocument 403 /~steve/courses/archive/test/yy
ErrorDocument 403 "My Infile Error 403"  #could put HTML in the ".."

======
<IfModule mod_autoindex.c>
 IndexOptions FancyIndexing IconHeight=16 IconWidth=16
</ifModule>

This is not needed on our server; but illustrates how to turn server options on
======

Require valid-user
Require all denied  [all users denied]
Require user steve  [only 'steve' allowed]

Filter classes of allowed users

======
DIR INDEXs
Options -Indexes  # should turns off all server-found indexes
But the cmd "Options" is NOT allowed locally by our server

DirectoryIndex dirs.php #Uses that one index file first [then defaults to rest]

IndexIgnore un*
	#Block files from showing in the auto-index file if it is used in current directory
	This stops the auto-index from listing files un*
	Even with just * you get an index page (but nothing listed)

======
FILE REDIRECTION [must be all on one line.]
Redirect   /olddirectory/oldfile.html    http://yoursite.com/newdirectory/newfile.html

======
Other stuff can be done.

MIME responses by browser to various suffixed files.

Block hot linking (of imgs)
