How to get hash in a server side language?

问题:

As far as I know, there's no way to get url hash in a server side language since hash urls are not being sent to the server side. One of my co-workers told me that it should be possible in java (jsp) or Ruby. Since I tested it on PHP, but it simply doesn't work. I googled about ruby and jsp, but had no luck. He also mentioned that the first access (http://domain.com/index.php#test ) is accessible from a server side.

in PHP, printing our $_SERVER variable doesn't have anything about hash

Is this really possible in other server side languages?

Short answer: no, it's a client side only thing.

Slightly longer: It's called Fragment identifier and is client side only - browser doesn't send that part of the url to the server. It's not possible in any language unless you are using some browser implementation (or software) which would send that part of url to the server.
