+ignore-persist { if | unless } <condition>
+  Declare a condition to ignore persistence
+  May be used in sections:    defaults | frontend | listen | backend

+  By default, when cookie persistence is enabled, every requests containing
+  the cookie are unconditionally persistent (assuming the target server is up
+  and running).
+
+  The "ignore-persist" statement allows one to declare various ACL-based
+  conditions which, when met, will cause a request to ignore persistence.
+  This is sometimes useful to load balance requests for static files, which
+  oftenly don't require persistence. This can also be used to fully disable
+  persistence for a specific User-Agent (for example, some web crawler bots).
+
+  Combined with "appsession", it can also help reduce HAProxy memory usage, as
+  the appsession table won't grow if persistence is ignored.
+
+  The persistence is ignored when an "if" condition is met, or unless an
+  "unless" condition is met.
