Hi, I'm running a multisite network, and per the instructions WordPress is installed in the root public directory. This works great for our two network sites, each of which have their own domain (through the MU domain mapper plugin). However, on the main site I want the WP blog to be at http://www.mainsite.com/ourblog, and leave the root domain available for other purposes. Normally on a non-MS installation I'd just put WP in the ourblog/ directory and be done, but that's apparently not possible with MS setups. Can I use Apache redirects or other methods to achieve the same effect?
I'm currently using multisite subdirectories, but can switch to using subdomains if it will make the problem easier.
