Redmine

Some users of my Redmine site have been complaining that the timeout occurs too quickly. I understand the security concerns but I would still like to extend the timeout time.

Does anyone know how to do this? I had a look through the config files and it didn't appear to have an option there.

If it matters I am running the website using Mongrel + Apache on a Ubuntu 7.10 server.

Thanks in advance for the help.
