Migrate SE content on using CiviCRM with nginx

Created by: seancolsen

This SE question asks about nginx and has quite a few up-votes:

https://civicrm.stackexchange.com/questions/27/is-civicrm-compatible-with-nginx

I think it'd be nice to add a section called "Webserver" here and copy some of that SE content over.

There's even a comment on the answer requesting that someone add this content to our docs!
