In Membrane Service Proxy, rule matching is the process of selecting a rule that will handle an incoming HTTP request.

The list of rules is defined in Membrane's configuration file, proxies.xml, as a list of

For an incoming HTTP request, the first proxy, serviceProxy or soapProxy matching the request will be selected. Whether a proxy is selected, is defined by its filter criteria. The filter criteria are a subset of

• incoming TCP port
• local IP address
• hostname (the HTTP request's Host header)
• request path (matched by a path prefix or a Java regular expression)

The first rule matching the request is selected.
