Remarks
A CookieContainer is a data structure that provides storage for instances of the Cookie class, and which is accessed in a database-like manner. The CookieContainer has a capacity limit which is set when the container is created, or changed by a property.
An instance of the Cookie class is added to the container based on its originating URI. It is added to an internal CookieCollection associated with the URI. A Cookie is retrieved from the container based on the URI as a CookieCollection, or as a string which can be used to submit HTTP WebRequests.
The CookieContainer has three properties that govern the volume of the content of the container: Capacity, MaxCookieSize, and PerDomainCapacity. These values have the default settings of 300, 4096, and 20 respectively. When a Cookie is added to the container, these properties are used to determine whether a Cookie already contained in the CookieContainer should be discarded to make room for the new one. The CookieContainer keeps track of each addition to ensure that neither the Capacity nor the PerDomainCapacity limits are exceeded. If one or both are exceeded, then Cookie instances held by the CookieContainer are removed. First, any expired Cookie is removed. If further capacity must be recaptured, then the least-recently-used CookieCollection is purged.
