The x flag of a directory means whether you can "chdir" into it or not, but nothing to do with the executables inside it. So you HAVE to make the directory `chmod +x'. As far as security reasons are concerned, people can't put things there and execute, even if the "x" flags are set, unless you mark the directory a script directory with "ScriptAlias". Also make sure that anyone can't save files with `executable' extensions (say .php .php3 or even .cgi if you have set extension based cgi) in that directory. Anuradha
