I'm trying to use such function as apc.filter in APC.But all, that i have done, didnt work

There are 2 task that I should done.

1)Need to include 1 catalog for caching.My code in apc.ini

```
apc.cache by default Off
apc.filter = "+/path1/.*"

```

Such option doesnt work.It's still caching

2)Need to exlude 3 catalogs on the server that shouldnt be cached,for example my code in apc.ini for such task

```
apc.cache by default On 

apc.filter = "-/path1/path2/.*,
apc.filter = "-/path3/path4/.*,
apc.filter = "-/path5/path6/.*"

```

Can somebody help me with it?plz
