+=== Configuring Default Servlet-Filter URL Patterns
+
+OpenIDM servlet filters can be configured to apply to specific URL patterns. When a filter configuration in `conf/servletfilter-*.json` does not specify an explicit `"urlPatterns"` list, OpenIDM builds a default pattern from the following `conf/boot/boot.properties` property:
+
+`openidm.servlet.alias`::
+Base path used when building the default filter URL pattern for REST API endpoints. Default: `/openidm`. Example override: `/myidm`.
+
+[IMPORTANT]
+====
+This property only controls which URL pattern is applied to servlet filters that do not have an explicit `"urlPatterns"` key in their filter config. It does *not* change the actual REST servlet registration, which remains at `/openidm`.
+====
+
+For example, to apply default filters to `/myidm/` instead of the standard path, add the following to `conf/boot/boot.properties` and restart OpenIDM:
+
+[source, console]
+----
+openidm.servlet.alias=/myidm
+----
+
+[NOTE]
+====
+Servlet filter configurations in `conf/servletfilter-*.json` that use explicit `"urlPatterns"` are not affected by this property. Only filters without explicit URL patterns use the value derived from `openidm.servlet.alias`.

 The Jetty configuration (in `openidm/conf/jetty.xml`) references the ports that are specified in the `boot.properties` file.
 
+In addition to the port numbers, you can configure the default servlet-filter URL pattern for the REST API via `conf/boot/boot.properties`. By default, the REST API servlet is mapped under `/openidm/`; this servlet mapping is defined elsewhere and is not moved by the `boot.properties` setting. The `openidm.servlet.alias` property only influences the filter URL pattern applied to that context. For details, see xref:appendix-jetty.adoc#configuring-rest-context-path["Configuring the REST API Context Path"].
