We run two web servers using a load balanced server. I have made some changes under customise. We discovered that some of my team were not seeing the changes (such as some new projects and some new resolution values). On investigation this was because they have been pointed to one of the web servers and I've been load balanced on to the other web server.

This all points to Gemini caching information rather than retrieving from the database each time. Can you explain what caching goes on please? How long is information cached for?
