why doesnt rails have forward/transfer ability?

Those of us that came from the Java and .NET  world, these framworks had 2 choices for sending the users browser to differnt places. Java has Redirect and Forward. Generally we preferred to use Forward in most cases because it saved a round trip back to the browser and was faster to execute and the context of the execution was saved. We used redirect sparingly, most often when we wanted the url to change explicitly to the end user.

C# also has Redirect and Transfer (which is the equivalent of forward).

So back to my question, rails supports redirect_to and is used in many examples in sanctioned rails books, why no forward or forward equivalent?
