Missing THttpClient.lua in Thrift binary unpack fails

[Daniel Rufus Kaldheim <daniel@...>]

I'm fairly fresh in both Thrift and Lua, and trying to write the
missing THttpClient.lua file for a project I'm working on.

I have managed to send data and to receive data through the
THttpClient:flush() function, but it stops there.

The problem seems to be in the THttpClient:read() function where it
reads part of the data that came through THttpClient:flush().

Is there anyone that can help me?

Thanks!
