Dynamic Redirects

By transparent, I mean passing the http header through nginx to other servers.  I'm just hoping nginx can help direct the request to the correct server.

Thx

Depends on what you mean by 'transparently routing' - is it choosing a 
different upstream (in case nginx is just a proxy) or redirecting to 
diferent host/server?

While you can prolly try use this 
http://github.com/chaoslawful/drizzle-nginx-module (although iirc the 
possibility to get a single return value as variable back is still in TODO)

I would imagine that using some dynamic language (like php or even the 
embeded perl (if you really want to do this on server side)) is more simple 
and while client is being redirected its still more or less transparent to 
him.



With the nginx inbuilt features (without the DB backend) its like this - a 
simple rewrite:

if ($http_user_agent ~ MSIE) {
  rewrite  ^(.*)$  /msie/$1  break;
}
