-option ignore-persist { if | unless } <condition>
-  Declare a condition to ignore persistence
-  May be used in sections:    defaults | frontend | listen | backend
-                                  no   |    yes   |   yes  |   yes

-  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.

-  See also : "option force-persist", "cookie", and section 7 about ACL usage.
