+The lifetime limit in minutes, or 0.
+This action reduces the lifetime of HTTP cookies coming from + the server to the specified number of minutes, starting from + the time the cookie passes Privoxy.
+ +Cookies with a lifetime below the limit are not modified. + The lifetime of session cookies is set to the specified + limit.
+ +The effect of this action depends on the server.
+ +In case of servers which refresh their cookies with each + response (or at least frequently), the lifetime limit set by + this action is updated as well. Thus, a session associated with + the cookie continues to work with this action enabled, as long + as a new request is made before the last limit set is + reached.
+ +However, some servers send their cookies once, with a + lifetime of several years (the year 2037 is a popular choice), + and do not refresh them until a certain event in the future, + for example the user logging out. In this case this action may + limit the absolute lifetime of the session, even if requests + are made frequently.
+ +If the parameter is "0", this + action behaves like session-cookies-only.
