/* * mod_userdir... implement the UserDir command. Broken away from the * Alias stuff for a couple of good and not-so-good reasons: * * 1) It shows a real minimal working example of how to do something like * this. * 2) I know people who are actually interested in changing this *particular* * aspect of server functionality without changing the rest of it. That's * what this whole modular arrangement is supposed to be good at... * * Modified by Alexei Kosut to support the following constructs * (server running at www.foo.com, request for /~bar/one/two.html) * * UserDir public_html -> ~bar/public_html/one/two.html * UserDir /usr/web -> /usr/web/bar/one/two.html * UserDir /home/ * /www -> /home/bar/www/one/two.html * NOTE: theses ^ ^ space only added allow it to work in a comment, ignore * UserDir http://x/users -> (302) http://x/users/bar/one/two.html * UserDir http://x/ * /y -> (302) http://x/bar/y/one/two.html * NOTE: here also ^ ^ * * In addition, you can use multiple entries, to specify alternate * user directories (a la Directory Index). For example: * * UserDir public_html /usr/web http://www.xyz.com/users * * Modified by Ken Coar to provide for the following: * * UserDir disable[d] username ... * UserDir enable[d] username ... * * If "disabled" has no other arguments, *all* ~<username> references are * disabled, except those explicitly turned on with the "enabled" keyword.
