Un truc important :

During searching for a virtual server by name, if the name matches more than one of the specified variants, (e.g. both a wildcard name and regular expression match), the first matching variant will be chosen, in the following order of priority:

the exact name
the longest wildcard name starting with an asterisk, e.g. “*.example.com”
the longest wildcard name ending with an asterisk, e.g. “mail.*”
the first matching regular expression (in order of appearance in the configuration file)
