In general, a method and apparatus for managing available cache memory in a browser are disclosed. Any document stored in a cache memory not having associated with it a strong reference is subject to being reclaimed by a garbage collector. The most recently requested documents, however, are stored in the cache memory with strong references associated therewith thereby precluding them from being reclaimed until such time as the strong reference is abolished. The strong reference is abolished when the document identifier associated with the document stored in the cache memory is not present in the document stack. Therefor, only the most recently requested documents remain stored in the cache memory depending upon the depth of the document stack.
