Psuedo Lua code:

Answer 1

If you are running your Lua code in Lua, you can use request_path() and request_uri() to read the URL, and global _GET for a parsed version that correspond to the URL get variables you mention.

Answer 2

Lua's standard library doesn't do networking. Check out LuaSocket.
