Comment enlever des taches de cire de chandelle sur une nappe, napperon, brique, gilet, linge?

Prenez un chiffon de type essuie-tout (Scott Towel, papier Scott), mouillez-le. Ensuite, prenez l'essuie-tout mouillé et étendez-le sur la tache. Prenez un fer ą repasser, et repasser par-dessus le papier essuie-tout. La cire fondra et restera collée sur le papier essuie-tout.

Incroyable mais vrai: ca fonctionne.

WebDAV, iCal, apache error 500 Lock, LockDB: This is driving me nuts: I follow the instructions to publish my iCalendars on my own Mac OS X client and I keep getting errors 500 in apache's error.log. What gives?

If you keep getting errors like this:

[Tue Mar  2 18:20:43 2004] [error] [client] The locks could not be queried for verification against a possible "If:" header.  [500, #0]
[Tue Mar  2 18:20:43 2004] [error] [client] Could not open the lock database.  [500, #400]
[Tue Mar  2 18:20:43 2004] [error] [client] (13)Permission denied: I/O error occurred.  [500, #1]

here is the deal: you probably made the same mistake I did when modifying httpd.conf. You highly likely have something like this:

DAVLockDB /Library/WebServer/DAVLock/

and the directory DAVLock exists, which means the Apache module can't write on top of it. The line must be say something like this:

DAVLockDB /Library/WebServer/DAVLock/DAVLockDB

and must not point to a directory! DAVLockDB is not a directory, it is two files: DAVLockDB.dir and DAVLockDB.pag.
