Issue replicating from behind firewall using http_proxy

Hi,

I am setting up a local repository for npm. The couchdb sync fine while not behind a firewall. But our hosted replication server is in a zone where we need to use http_proxy for hitting the external sites.

For couch db replicate I tried with proxy settings similar to given below, but all the combinations that I tried did not work..

These are the several options that I tried. Could someone please help to fix this? or let me know if I am missing something.

1.
curl -x http://<proxyurl>:80 -X POST http://10.137.115.211:5984/_replicate -d@npmRegistry.json -H "Content-Type: application/json"

cat npmRegistry.json

{"source":"http://isaacs.iriscouch.com/registry", "target":"registry", "continuous":true, "create_target":true}

2.

curl -x http://<proxyurl>:80 -X POST http://10.137.115.211:5984/_replicate -d '

{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry", "create_target":true}

' -H "Content-Type: application/json"

3.

curl -X POST http://10.137.115.211:5984/_replicate -d '

{"source":"http://isaacs.iriscouch.com/registry/", "target":"registry", "create_target":true, "proxy":"http://<proxyurl>:80" }

' -H "Content-Type: application/json"

4. I tried from the web interface of couched

5. I tried with the npm replicate application, after setting up npm set config http-proxy

All these options did not work.
