I have an unsubscribe form that I'm hoping to be able to provide a url to in emails - with the bulkmail group id included in the url and accessible via the globals_get keywords.
Under one root url, the globals_get keyword was not working due to caching
E.g. webcms.waikato.ac.nz / ... / stories-unsubscribe-form?category=244303 was giving me a result for globals_get_category
however www.waikato.ac.nz / ... / stories-unsubscribe-form?category=244303 was not.
Setting the cache manager to not cache the page in question remedied the problem.
