In Firefox 3.0.x I was using nsICacheService.createSession("image-chrome") session object to remove chrome images from cache. Since Firefox 3.1.x this doesn't work anymore. Could you advise - is this a bug? Or what should I use to remove chrome images from cache?

Reproducible: Always

Steps to Reproduce:
1. Execute the code listed in Additional Information below.

Actual Results:  
Chrome image isn't removed from cache.

Expected Results:  
Chrome image is removed from cache.

    var cacheSession = Components.classes["@mozilla.org/network/cache-service;1"]
          .getService(Components.interfaces.nsICacheService)
          .createSession("image-chrome", Components.interfaces.nsICache.STORE_ANYWHERE, false);
    try {
      var entry = cacheSession.openCacheEntry(imageURL,
                    Components.interfaces.nsICache.ACCESS_READ, false);
      entry.doom();
    }
    catch(e) {}

[Matthias Versen [:Matti]]

imagelib has a new disk cache implementation

Images aren't stored in the memory cache any more; instead, you can use imgICache::removeEntry(). imgICache is available from @mozilla.org/image/cache;1. Just call imgICache::removeEntry("chrome://path/to/image") and you'll be set.

(This will also work in Firefox 3.0.)
