This can be done by Apache 1.3.3. Apache supports virtual hosts, many
hostnames are mapped to a single IP address. Apache's mod_rewrite and
mod_proxy module can rewrite URL requests to real servers based on
different hostnames, forward requests to the chosed server, get result and
return the result back to the client.
However, since it is done in application level, the processing overhead is
high, it needs to parse and rewrite URL requests, establish another TCP
connection to get the result from the chosen server and return it to the
client. The scalability of this method is not very good.
