Re: Redirect from _list function?
Guys, I've started a ticket for this: https://issues.apache.org/jira/browse/COUCHDB-514 I don't know what level of effort would be required to fix this, or if this is even compatible with the current view server protocol. I'm motivated to solve this, but I'd need some coaching from someone with more knowledge of CouchDB view server internals.

Fwd: Redirect from _list function?
Hey guys, I need to find a way to do a redirect from a _list function after calling the getRow() function. After looking at render.js for a while I can't see how to solve this without at least adding to the API. Basically, I think that calling getRow() shouldn't cause the view server to send the headers (or awaiting chunks) unless we've already called send() or something like that. That way, we can return from the _list function after iterating to the first row that should redirect. (I'm not sure if this is a breaking change from the current semantics, however...)

Re: Redirect from _list function?
its been awhile since i studied the Erlang side of this, but IIRC, once getRow() returns, the response has started which means that you can't send a redirect. To get it working proper then would require a bit of a patch to wait on starting the response until the first output from the _list function.

https://issues.apache.org/jira/browse/COUCHDB-513?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jason Davies closed COUCHDB-513.
Resolution: Invalid
To send headers you need to use the start() function for _list, e.g.
function(head, req) {
start({code:301, headers: { 'Location': 'http://www.google.com/' }});
}
