ngx_mongo is an upstream module that allows nginx to communicate directly
with MongoDB database.
This module is considered stable and it's compatible with the following nginx releases:
- 1.1.4+ (tested with 1.1.4 to 1.1.19),
- 1.2.x (tested with 1.2.0 to 1.2.2),
- 1.3.x (tested with 1.3.0 to 1.3.2).
NOTE : At this time we are not actively developing this module, and don't plan on returning to it.
