While this caveat behavior is known and possibly relied upon by lsl scripts. Nobody should be writing a slua script expecting this security issue to exist. So if possible could a ll.HTTPRequest from slua, only trigger the http_response event in the slua script making the request. Or a dataserver request also respond only to the requesting script. Not in any other, script regardless of their platform runtime. This might be a slight pain to implement to keep the behavior for lsl on luau scripts, but I think worth it for slua Test Place 2 scripts in a prim save them with the following content ll.HTTPRequest("https://secondlife.com",{},"") function http_response(id,stat,meta,body) ll.OwnerSay(`{ll.GetScriptName()} = {stat}`) end Note that on saving of the second script you get 2 owner says, one from each script stating the response status. Ideally this behavior should be avoided for slua. Alternate suggestion It was suggested it may be possible to instead add a new HTTP_* flag Something like ll.HTTPRequest( "https://secondlife.com", { HTTP_PRIVATE_REQUEST, TRUE }, "" ) This would not work for dataserver events though

Using strict type checking doesn't display warnings in the Script Warning/Error window --!strict local function add(a: number, b: number): number return a + b end local result1: number = add(3, 4) -- Should work fine local result2: number = add("3", 4) -- Should trigger a type error in strict mode This code in Luau/Roblox displays this warning: Type Error: (8,29) Type 'string' could not be converted into 'number'

The SLua code below demonstrates the problem. Two vectors, multiplied, results in a vector answer rather than a number. v1 = vector(9, 2, 7) v2 = vector(4,8,10) v3 = v1 * v2 ll.OwnerSay(typeof(v3) .. ": " .. tostring(v3)) Program output: vector: <36.00000, 16.00000, 70.00000> Reason for identifying as a bug: The SL Wiki indicates that the dot product should return the sum of the products of the vector elements. In this case, the expected result should be 122.0. What is returned instead is simply the vector of the products of each element.
