WordPress resolves paths relative to the WordPress site root. In most cases the WordPress site root and domain root are the same, but in other cases wordpress is installed in a subpath. For example, a wordpress site may exist at http://<mydomain>/wordpress which would cause the wordpress site root (/wordpress/) to be different than the domain root (always /).
To allow references outside of the wordpress site root, paths referenced by the IntraWeb WordPress are resolved in the following manner with few exceptions.
If a url begins with:
- / – relative to the domain root
- http:// or https:// – absolute URL
- other – relative to WordPress site root.
If a path starts with ~, it will be treated as an expansion path. Several predefined expansion paths must be defined in config.php, but user defined ones can also exist.
For example, given the path:
~IWLib will be replaced with the value specified in config.php for IWLib resulting in something such as:
Expansion paths are processed before other merges and can be further merged.
