Hmmm... I did all that and I can't seem to find any indication that it's working... The cache directory is created and a few small files are added (look like headers) but the cache directory does not increase in size. du -h on that directory shows it is not getting any bigger, it's like 240K...
Can you walk us through any tips, tricks, gotchas, sample configs, etc. ? Walk us through enabling caching as if we knew nothing whatsoever about LSWS or Apache so we're sure we aren't missing anything? ;-)
