Example of Website sided code for HTTP requests from ROBLOX?

In the Wiki tutorial for HTTPAsync how to use, we are given an exmaple of how to use POST and GET to a certain website.

However, from my knowledge, just sending a POST request will not do anything. The POST request, once received by the website, should be stored in a $_POST variable. This was verified by myself individually setting up the website, and seeing that after one test of the script, the website had ABSOLUTELY NOTHING changed to it

Yes, I have HttpService enabled, I have checked that.

Here is the code from the wiki that I copied just as a beginner step to see how this works.

myTable = {}
myTable["exp"] = 1100
myTable["gold"] = 999
myTable["swordID"] = 1000398
 
-- Initialize an HTTP Service pointer
hs = game:GetService("HttpService")
-- Encodes the Table into a JSON string.
myTableJSON = hs:JSONEncode(myTable)

hs:PostAsync("http://--[[Link hidden for privacy reasons]]", myTableJSON)




wait(20)

myTableJSON = hs:GetAsync("http://--[[Hid link for privacy reasons]", true)
-- Decodes the JSON String we just received into a Lua Table.
myTable = hs:JSONDecode(myTableJSON) --Errored saying that it could not be converted, which I'm assuming is due to the fact that my website literally had nothing.
-- Returns myTable, which looks like {"exp"=1100, "gold"=999, "swordID" = 1000398}

for i, v in pairs(myTable) do
	print(i, v)
end

I just need one example that shows both the response to a POST and GET request, and I can work MILES off of that. Thanks in advance!
