Global Error Docs
Currently on my setup I'm doing a global error docs setup if the user doesn't own their own errordocs.
I extend this setup to the index pages as well, basically I take out the index.html from their directories if they don't own their own global docs and my special centralized index.html is used if I get a 404 thats references the root index page. My code also checks when removing user owned error-docs if any of the installed files are "identical" to the ones installed, if so it removes them.
The main advantage this has over the current setup is, if you modify the existing global index or errordocs page, it will automatically go into affect over your entire site without having to copy your errordocs into all the hosted sites.
Anyone else want a feature like this?
