In the current version I don't know how to create a QB URL that will direct to a specific configuration. I can only use the URL from the build log - which is somewhat cryptic.
I think a URL like
http://quickbuild/app.do?goto=root/product/module or http://quickbuild/app.do?goto=root.product.module
that will take you to the root.product.module configuration, will make it easier to create links to the configuration, without knowing the configuration id.
The first option (with /) is better, because then the url reflects the module structure, and can be easily bulit, especially with Maven
