I just tried to perform a GET request in a Batch and was told (well, the API responded ;) that it was not allowed. Is there a reason for this? I'm trying to get aggregate data for my content. So I want to do a get where I pass count:1 and limit:0. I need to sum up the count for 3 types of data. Obviously I could do 3 HTTP calls, but one batch could would be better I think.
