Yes. You can use a persistent cache. See the client option in the  
ClientStorage constructor and in zConfig.

This might not be a good choice for a CGI script though. In the  
current implementation, there is no locking of the cache file and it  
is likely to be corrupted if 2 or more processes open it at the same  
time.
