Q:

Choosing the post-build server based on variable value

I have two server as a target machines: dev and production.  They're both connected to the Jenkins by "Publish over SSH" plugin. 
And now I want to choose which one is being used for a target.  But in project configuration, the only thing I can do with target server is to use it as by choosing from fixed list which - AFAIK - is not parametrized. 
What I want - as a parameter I choose dev/prod and - based on that choice - I want to specify a target machine. 
Is it possible to achieve using pure-Jenkins solutions or plugins?

Ok, found the solution: https://wiki.jenkins-ci.org/display/JENKINS/Flexible+Publish+Plugin
Will test and mark as accepted if it's correct.
