[openamq-dev] Content Based Routing

[Martin Sustrik]

Malinga,

Have a look at "headers" exchange. Each message has "headers" - actually 
a table of name-value pairs, and headers exchange allows for routing on 
such a table. Say, you can create bindings like "all call options with 
underlying stock equal to VOD" or "all forex quotes with base currency = 
USD and quote currency = GBP" etc.
