We currently have a multisite wordpress solution implemented. We have created a separate application in raw php for searching one of the tables within the installation for one of the sites on the multisite installation. Is there anyway that we can have this application reside within the multisite installation but to where it's not accessible by all other sites on the multisite.
For example, if I create a new directory
/app within the document root, I can access the application without problem, however, so can every other site that is hosted within the multisite installation. We would need some way of making particular directories only accessible to the site which should have access to them.
Has anyone done this before? Does anyone have any suggestions?
