set SlaveOK?

[e1ven]

Is it possible to add a flag to enable SlaveOK?
For 99% of my files, I don't mind if it loads off a replicaset. In fact, I prefer it!
The files are static anyway, and I'm already hitting a MongoS instance, rather than mongod directly.

It's possible, but not until the C driver supports the same setting. You can watch this issue here:
https://jira.mongodb.org/browse/CDRIVER-68

Once that's resolved, I'll add.

Hi, I forked https://github.com/cheeming/nginx-gridfs and applied a patch based on mongodb/mongo-c-driver@f063fb1. I have not done extensive testing but some might find it useful.
