<Host> element is used to apply content rules to requests to a specific virtual host (or often to the two virtual hosts running on the default ports).
scheme("http" or "https")
XML attributes corresponding to request mapper properties are used.
Zero or more of these "overrides" to match specific content on the virtual host can be included.
Matching is done within a
<Host> element as follows:
1. First, by examining
<Path> elements in order.
2. Then, by checking any
<PathRegex> elements in order against the part of the path that was not matched in the first step.
3. Finally, by examining any
<Query> elements in order.
Once a matching child element is found, the process steps "into" that element and no other siblings will be applied. Thus, siblings cannot overlap.
