Subject [jira] Commented: (COUCHDB-883) Wrong document returned due to incorrect URL decoding
Date Fri, 10 Sep 2010 07:53:33 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12907922#action_12907922
] 

Sebastian Cohnen commented on COUCHDB-883:
------------------------------------------

RFC2396: G.2. Modifications from both RFC 1738 and RFC 1808

"The plus "+", dollar "$", and comma "," characters have been added to those in the "reserved"
set, since they are treated as reserved within the query component."

Therefor you need to URI-encode the plus (+) character according to the RFC.

>             Project: CouchDB
>          Issue Type: Bug
>          Components: HTTP Interface
>    Affects Versions: 1.0.1
>         Environment: Kubuntu 10.4, Firefox 3.6.8
>            Reporter: Taras Puchko

> I have two documents in my database: "a b" and "a+b". The first can be retrieved via
"/mydb/a%20b" and the second via "/mydb/a%2Bb".
> When I enter "/mydb/a b" in the browser it automatically encodes it so the correct document
is returned. But when I enter "/mydb/a+b" the URL is sent intact since "+" is a valid character
in a path segment according to [1]. The problem is that "GET /mydb/a+b" makes CouchDB return
the document with id "a b" and not the intended one, which is against the URI spec .
> For an informal description of URL encoding one may refer to [2].
