Alternatively, you may have kept the same database handle open across a fork call, which this mentions as the source of problems, so don't do that either.
So, this may partly be just my ignorance. I am assuming that Apache2 is the forking server here. After all, it spawns little children to manage the web queries.
I am not sure how things work under a mod_perl (or even a fastcgi) kind of persistent perl environment under Apache2. I am assuming that my entire application is compiled and loaded when the server starts. At this point, a db handle is not created. Then, a user queries, which causes a db handle to be created. Since I don't want a new db handle created for subsequent queries by the same user, I reuse the db handle. And, I don't disconnect the db handle, because, if I do, then subsequent queries will fail. How do I ensure that a persistent, unique db handle is created for each user to my web site?
