MarkLogic 10 Product Documentationrest:matching-request
rest:matching-request( $options as element(rest:options), $match-criteria as xs:string+ ) as element(rest:request)?
Summary
This function returns the request element in
the options node that matches the specified URI. If
you only specify options parameter, all criteria in the request
environment are considered. If you supply specific criteria, the
filter is less strict, allowing the same options block to be used
for simple url-based rewriting as well as request processing.
| Parameters | |
|---|---|
| options | The options node. |
| match-criteria | Criteria to be used in matching request rules. By default, all are used. Supply one or more of: "uri", "accept", "conditions","method", "params". |
