-------------------------------------

             Summary: Using rewrites results in duplicate CORS header
                 Key: COUCHDB-2292
                 URL: https://issues.apache.org/jira/browse/COUCHDB-2292
             Project: CouchDB
          Issue Type: Bug
      Security Level: public (Regular issues)
          Components: HTTP Interface
            Reporter: Nathan Korth


I have configured my Couch instance to allow cross-origin requests from localhost:8080 using the following snippet of local.ini:

{code}
[httpd]
enable_cors = true

[cors]
origins = http://localhost:8080
{code}

When I make requests for normal views, Couch sends the Access-Control-Allow-Origin header as expected, and everything works. However, I also have a simple rewrite that points to a view, and when I request the rewrite (which does work outside of a browser), I get a header that looks like this:

{code}
Access-Control-Allow-Origin: http://localhost:8080, http://localhost:8080
{code}

This causes Chrome to complain with the following error:

{code}
XMLHttpRequest cannot load http://my-couch-instance/rewrite-base/rewrite. The 'Access-Control-Allow-Origin' header contains multiple values 'http://localhost:8080, http://localhost:8080', but only one is allowed. Origin 'http://localhost:8080' is therefore not allowed access.
{code}
