Below is the code I use within my projects, perhaps it can be adapted for Knop. It runs within the context It tries to find a index.lasso file (or a permutation), if it can't find one, it assumes the path is virtual and has a place to handle that. It then overloads the response_filepath with either the found index.lasso file or the file that should handle the virtual path.

Any tag prefaced by lp_ is a ctag that you can grab here:

Any improvements are welcome!
