Drupal - robot.txt - Multisite, single db challenged
After several different configurations, I have not be able to get a robotstxt to function on a site by site basis. Part of the confusion is that multisite, single db, single codebase, with sites/mysite.com/modules/robotstxt installation instructions are a bit varied and I may just not have gotten the correct combination of tricks (serveralias, synlinks,staged installation of modules...). My primary difficulty is understanding how drupal manages the 'variable' table.
