Template class for substituting request properties into an HTML page.
This class is used by the TemplateHandler
The following request properties are used:
- query
- The query parameters are placed into the request object,
prefixed by the value assigned to "query".
- headers
- The mime headers are placed into the request object,
prefixed by the value assigned to "headers". The values:
url, query, method, and version are copied from the request
object into the properties. The clients IP address is
saved in the "address" property.
- url.orig
- If set and "headers" are requested, this value is used as
the
url
instead of the one in request.url.
A new HTML tag,
<property>
is defined. It takes the following
tag attributes:
- name
- The name of the property in
props
to replace the property
tag with.
- default
- The value to use if the property is not defined.
If no
default
is specified, the empty
string is used instead.
- convert
- The value is converted before substitution into
the content. Convert accepts either:
- convert=htmlProtect plain text by escaping the
characters " < > and &.
- convert=urlMake sure the string is suitable
for use in a url or query string.

This gets called at every page, at the beginning. See if we should add
the mime headers and query parameters into the request object
Convert the html tag "property" in to the request's property
Parameters: key The name of the property to substitute. Variable
substitution using the style described in
Format is permitted, e.g.:
employee.${id}.last
Insert a literal ">"
Insert a literal "<".
Using the current scheme, there is no easy way to substitute into
a tag parameter. So we'll invent a "magic" tag (called tag)
that will allow us to create entities dynamically. Thus values
can be substituted into entities by escaping the entity as in:
<tag>a href=<property href></tag>
