Hi Giuseppe, Your assumption that SITE is a copy is incorrect. Each iteration through the FOREACH body block, SITE is set to a new url. Essentially, SITE is a pointer to the original url. There is no copying happening. Therefore, INSERT, REMOVE and APPEND are all working on the original urls. Anton.
