Oh yes, I think I didn't understand you answer.. but now all became=20
clear in my mind. I'm afraid that using this solution maybe cause an=20
increase on storage processor load, because for every request the scrip=
t=20
must be executed. I already have some issues with server availability,=20
and perhaps the solution of a problem becomes the worsening of another.

Still thanks for the reply and thanks for helping to clear my mind.
