In the Active4D documents there is an example regular expression
pattern like this:
$pattern := "|^(http://)?([^/]+)(/4dcgi)?([^?]+)(\?)?(.*)|i"
In this example, I notice the use of the "|" (pipe) around the
pattern. Is this an A4D specific thing?
From the PHP perl-compatible regular expression docs:
"The syntax for patterns used in these functions closely resembles
Perl. The expression should be enclosed in the delimiters, a forward
slash (/), for example. Any character can be used for delimiter as
long as it's not alphanumeric or backslash (\). If the delimiter
character has to be used in the expression itself, it needs to be
escaped by backslash."
Since the pattern in the example above uses a ton of '/' characters,
it saves a lot of backslashing to use a different delimiter.
