I have seen this question asked in other places on this forum but without any workable solution. Here is the scenario. We are considering moving our university website into wordpress, but the one thing that is holding me back right now is the ability to have nested sites, at a level higher than the first "folder" level.
Consider this URL: http://www.sph.uth.tmc.edu/research/
This needs to be a site managed by our Office of Research. No problem, right? Well add to that, that I need this URL: http://www.sph.uth.tmc.edu/research/centers/cep/ to be another site, managed by a totally different group. I can lose the "centers" portion of the URL, but that seems incidental to this requirement.
Categories and adding things to the permalink structure is not really an option because these need to be distinct sites, managed by different, but sometimes overlapping groups.
One solution that I have seen is doing nested installs. This is a bad idea for us because I am a 1-person web department and don't have the resources to manage 10+ installs of wordpress.
Given that worpress already has the ability to emulate folder structures, this should not be a huge undertaking. I am willing to entertain ideas of using the web.config (I am on IIS) and the URL rewrite module to accomplish this, but I am not 100% sure how to move forward.
