Dynamically adding app servers behind web server

[Ryan Murphy]

We have an application that we use for document conversion.

It has a web server and can have any number of app servers sitting behind it.  The webserver has one configuration file with a parameter that states what app servers it should be contacting.

Is there a way in Puppet that I could dynamically update that parameter as app servers are created / deleted?

I've looked at exported resources, but I'm just not sure how to use them to do what I want to accomplish.

The puppetlabs/haproxy[1][2] module might be of interest to you. It uses
that approach to allow dynamic management of HAProxy proxy backend members.
