If absolute is set to "yes" , interpret the url attribute as a path on the filesystem,

method sets the HTTP method to use when passing the request to the next step in
a pipeline. More about pipelines can be found in “Advanced URL Control” on

A forward element can contain the following additional children:
• The add-parameter element lets you add or override a request parameter:
<add-parameter name = string
value = string />
• The set-attribute element sets a request attribute :
<set-attribute name = string
value = string />
You can inspect request attributes through eXist's request extension module.
There's more about request attributes and how they differ from parameters in
“The request Extension Module” on page 209 .

• The set-header element sets an HTTP header field:
<set-header name = string
value = string />
