I have problem with poll module (in 4.6.3) when cache is enabled and server load problem when cache is disabled. Anonymous users see 'random' view for the poll block on pages, for example; on the main page - results, some category - vote form, another category... Is the block cached with the page? Is the cache page-oriented? If so, is it a good idea to put the poll block's contents in an iframe or? I hope I'll have time to dig a bit deeper soon... Thanks in advance.
