Muharem Hrnjadovic commented on COUCHDB-883:
--------------------------------------------

FWIW, an URL like http://localhost/a+b is left alone by apache2 i.e. I see the following entry in /var/log/apache2/access.log:

127.0.0.1 - - [10/Sep/2010:05:13:30 +0200] "GET /a+b HTTP/1.1" 200 294 "-"

Also, a file with that name (a+b) is served correctly.

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

> 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].
