It would be nice if there was some mention of the "fixes" to the old workarounds on the wiki, instead of just deleting any mention of the workarounds entirely. As I can't even edit my own wiki description anymore, it will have to be someone else. Or maybe documentation is just more optional than it used to be.
Also, the keys I'm getting in http_response don't match the key returned by the llHTTPRequest at all. Makes it difficult to catch responses when they come back with totally different IDs. (This is returning 499 codes, but I don't know why the keys wouldn't match)
