Adding entry to Firefox cache from an XPCOM component

The nsICacheSession has a method openCacheEntry() which returns an existing cache entry. Is there a method such as createCacheEntry() that will create a cach开发者_开发知识库e entry. I want to create an XPCOM object that will read files from disk and write them to Firefox cache.

Thanks

As stated in MDC nsICache interface reference opening an entry with ACCESS_WRITE will create the entry if it doesn't already exist (if it already exists, the entry will be doomed so you can replace it with a new one).

Perhaps a little too late for the original poster, but this can be useful for other people out there.
