plugin wp fastest cache: Exclude projects?

[dabu]

I need to exclude all the projects from being cached by the plugin you recommend for a faster website. Can I do this by excluding posts (Beiträge), are these the projects?

I need to exclude them because of some php loading from an external service, which is not correctly updated if caching is on (strangely, only on smartphones, not on desktop).

yea should be "beiträge". i just renamed posts to projects and in german that should be beiträge
