As far as I can tell, the actual URL of the cached object is not stored in memory and this operations requires scanning the volumes and reading the metadata for each HTTP object from disk.I think that you'd have to build an index in memory or in the cache. I don't think you can iterate the HTTP cache from a plugin, so you might have to hack the core :(
It should be possible to traverse the entire cache, but it'll be incredibly expensive and slow on large caches. See TSCacheScan() and the cache_scan plugin for more details on scanning the cache.
