True, but the same cannot be said for open sockets, which is the issue here. If you open a database connection during startup and cache it yourself (as opposed to letting Apache::DBI do it), you will end up trying to use the same connection from multiple children. Similar problems crop up with XS modules that have data structures in C that the perl code just points to -- they don't work across forks. > You ought to check out DBIx::Class.

I don't believe it's possible for them to share the same connection safely under FastCGI, since it is multi-process, just like mod_perl with the prefork MPM. The DBIx::Class code never shares connections across processes or threads. - Perrin Using Tomcat but need to do more? Need to support web services, security?
