However I failed to use libNew and TMapFiles with Carrot ( I'll look at this problem again). Another solution would be using TFile with file-locking or with semaphores. As a starting point would be implementaion of lock ing Carrot serever-side caching.

All global instances (like gDirectory, gROOT, gApacheBrowser etc) are not shared and are different for each apache subprocesses > > If there isn't already a mechanism in place, [is it possible and] would > there be any argument against adding a TMap like caching object that > scripts could store TObjects in?

Need to be investigated. Regards. Valeriy
