11:30 - Embedding Programs in Apache Traffic Server - Bhaskar Sengupta, Principal Engineer, Yahoo

Apache traffic Server (ATS) powers many, if not most, of proxy implementations in Internet today. These are used for many reasons including reverse and forward proxying.  There are certain requirements that cannot be met through writing configuration file alone, however complex those may be. Then we need programs. Till date this would mean writing ATS plugins in C / C++. But with the ATS Lua plugin one can now embed Lua scripts in ATS. Lua is a lightweight yet powerful language. And it is easy to learn.

Bhaskar, a well known face in #lspe-in community, would showcase how quickly one can write such programs, test them and run in production.
