What you really want to handle, is concurrency. Asido from IRC have rewrote vicious gmail using luasocket. [0] He said it returns immediately, if the network is completely down. But still hangs if the network is slow. The problem is that luasocket doesn't asynchronous http calls. You have to use raw tcp sockets and implement http yourself (not so good idea) [1]
I also test other libraries: - libcurl: blocks too - lualibevent & luaev: no http There are some node.js clones out there like LuaNode. But they embed lua instead of providing a library. The best idea maybe is writing an asynchronous lua bindings for one of the network libraries out there. (maybe libsoup[3]) The lack of lua libraries sucks sometimes. Anyone who a have idea, how to solve this problem? And I don't want solutions like dump curls output to disk.
