This appears to match "www.yoyodyne.com", "www--.yoyodyne.com",
"www-------.yoyodyne.com", and so on, if interpreted as a regex.
not really. it would not match www.yoyodyne.com.
Why not?
i may be wrong, but if - is not a special charachter, the previous
expression should match only domains starting with www- and ending
in [randomchar]yoyodyne[randomchar]com.
"*" matches the previous character repeated 0 or more times. This is
in contrast to wildcards, where "*" alone matches any character 0 or
more times. (This is part of why regexps are often confusing to
people used to the much simpler wildcards.)
Therefore "www-*" matches "www", "www-", "www--", etc., i.e. Scott's
interpretation was correct. What you describe is achieved with the
"www-.*.yoyodyne.com".
you're right. ok, it is official. i must stop drinking this much - it
just doesn't work. i have to start drinking less or, even better, more.
