Now it becomes possible to reuse the quotes within arguments, allowing
the parser to distinguish a ',' or ')' that is part of the value from
one which delimits the argument. In addition, ',' and ')' may be escaped
using a backslash. However, it is also important to keep in mind that
just like in shell, quotes are first resolved by the word tokenizer, so
in order to pass quotes that are visible to the argument parser, a second
level is needed, either using backslash escaping, or by using an alternate
type.
For example, it's possible to write this to append a comma:
http-request add-header paren-comma-paren "%[str('(--,--)')]"
or this:
http-request add-header paren-comma-paren '%[str("(--,--)")]'
or this:
http-request add-header paren-comma-paren %[str(\'(--,--)\')]
or this:
http-request add-header paren-comma-paren %[str(\"(--,--)\")]
or this:
http-request add-header paren-comma-paren %[str(\"(\"--\',\'--\")\")]
Note that due to the wide use of '\' in front of parenthesis in regex,
the backslash character will purposely *not* escape parenthesis, so that
'\)' placed in quotes is passed verbatim to a regex engine.
