   An interesting observation is that a 403 HTTP response, which a `forbidden` could generate for individual docs will trigger a cookie refresh.
   
   However replicator, in the normal case would write documents using a `_bulk_docs`  endpoint and the result of that is `201` even though some documents in the batch failed with a `forbidden` error.
   
   It is possible to trick the replicator to use single requests if attachments are used. Indeed, I had waited till the after the session expired and added a document with an attachment to the source:
   
   ```
    curl -s -XPUT adm:pass@localhost:15984/srcdb/1/att1?rev=1-66e95cbbe626e928747ecc225341b2d6 -H 'Content-Type: application/octet-stream' -T 1mb
   {"ok":true,"id":"1","rev":"2-3dec55150ee06ac046419c71f00f5351"}
   ```
   
   The script was running in the part with long sleep but as soon as the attachment was added, the session was refreshed and the a few writes succeeded:
   
   ```
   DocID: 4
   Doc added to source, sleeping 7 seconds
   Getting doc from target:
   {"error":"not_found","reason":"missing"}
   
   DocID: 5
   Doc added to source, sleeping 7 seconds
   Getting doc from target:
   {"_id":"5","_rev":"1-66e95cbbe626e928747ecc225341b2d6","name":"adm"}
   
   DocID: 6
   Doc added to source, sleeping 7 seconds
   Getting doc from target:
   {"error":"not_found","reason":"missing"}
   ```
