The most important part of the path.xml file is the list of <map> tags, or mappings, each of which specifies a directory, host, or domain that PopChart Image Server has permission to access. Map, which is a subelement of PathMaps, consists of three attributes: Name, Path, and Action.
This specifies the name for the mapping. Except for the DefaultRead and the DefaultSave names (which specify the default directory for any files that are loaded and any files that are saved, respectively), this attribute has no other significance. In future releases, it may become an optional alias for that path, so you may want to keep that in mind as you name each mapping.
This specifies the path that this mapping allows access to. You should set the value of this attribute to either a local path, host name, or IP address.
A path can be absolute or relative. A dot slash./ before the path makes it relative to PopChart Server's document root directory (usually chart_root). You cannot use two dots ../ to go up a directory.
Wild cards are allowed. In local paths, they allow PopChart Server to access all of the subdirectories of the specified path. For example, in the DefaultRead mapping of the default path.xml, ./* means that PopChart Server can access any file in the document root directory, or in any of its subdirectories.
In URL, wildcards can specify that access permissions should be given to an entire domain or subnet. For example, *.mycompany.com gives access permissions to every host in the mycompany.com domain. 12.1.*.* gives access permissions to every computer in the 12.1.x.x subnet.
This specifies the action that the mapping allows. Currently, there are three mappings:
Allows PopChart Server to load files from the path specified by the Path attribute.
Allows PopChart Server to save to the path specified by the Path attribute.
Allows PopChart Server to load files from the host, domain, IP Address, or subnet specified by the Path attribute.
