FSF for network cipher

Hi

I?m developing a nredir Filter to cipher the files stored on net
resources. I?m having a problem with the Cache Manager. When I filter
a read operation on a file for data that is not in cache I see a new read
operation I assume is caused by the cache manager. If I try to decipher
both operations, I decipher the data twice.

I have to differentiate between a normal file read operation (cached or not
cached)
and the cache manager calls, to cipher or decipher only de cached calls and
the
normal read operation that is not cached.

I thought only testing the IRP_NO_CACHE flags it was enough
but this is not true.

Thanks in advance.
