Hi,

We are using mongodb with some node.js application and need to figure output to push the read connections to secondary/nearest secondary.

We tried couple of options with mongodb url
1) With replica set as below
mongodb://renewmedb_rw:renewmedb_rw123@renewmedbprd003las.io.askjeeves.info:27017/renewmedb?replicaSet=rs1&w=5&ReadPreference=NEAREST"

2)mongodb://renewmedb_rw:renewmedb_rw123@renewmedbprd001iad.io.askjeeves.info,renewmedbprd002iad.io.askjeeves.info,renewmedbprd003iad.io.askjeeves.info,renewmedbprd001las.io.askjeeves.info.renewmedbprd002las.io.askjeeves.info,renewmedbprd003las.io.askjeeves.info:27017/renewmedb?replicaSet=rs1&readPreference=secondary"

3) "mongodb://renewmedb_rw:renewmedb_rw123@renewmedbprd001iad.io.askjeeves.info,renewmedbprd002iad.io.askjeeves.info,renewmedbprd003iad.io.askjeeves.info,renewmedbprd001las.io.askjeeves.info.renewmedbprd002las.io.askjeeves.info,renewmedbprd003las.io.askjeeves.info:27017/renewmedb?readPreference=secondary&slaveOk=true"

All the connection goes to primary in case of replicaset and without replicates also it goes to primary alongwith all secondary because those are the part of URL.

Can someone help us to provide some details so we can push all reads just to secondaries?

Thanks,
Amit
