Subject [jira] [Created] (HTTPCLIENT-1212) SET-COOKIE header with RFC1036 Date cannot be parsed / is dropped
Date Tue, 03 Jul 2012 14:40:29 GMT
Achim Westermann created HTTPCLIENT-1212:
--------------------------------------------

             Summary: SET-COOKIE header with RFC1036 Date cannot be parsed / is dropped
                 Key: HTTPCLIENT-1212
                 URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1212
             Project: HttpComponents HttpClient
          Issue Type: Bug
          Components: HttpClient
    Affects Versions: 4.2 Final
         Environment: Linux version 3.2.0-3-amd64 (Debian 3.2.21-3) (debian-kernel@lists.debian.org)
(gcc version 4.6.3 (Debian 4.6.3-8) )
            Reporter: Achim Westermann


Problem: Server sends a cookie in RF-1036 date: 

DEBUG [org.apache.http.wire] << "HTTP/1.0 301 Moved Permanently[\r][\n]"
DEBUG [org.apache.http.wire] << "Server: Apache-Coyote/1.1[\r][\n]"

DEBUG [org.apache.http.wire] << "Proxy-Connection: keep-alive[\r][\n]"
DEBUG [org.apache.http.wire] << "[\r][\n]"

The RFC2109Spec.java uses the DateUtils.PATTERN_RFC1036 in the default set for cookie dates.


Method RFC2109Spec.parse(Header, CookieOrigin), line 108 uses: header.getElements();
This method sees the ',' as the delimiter between two header elements (BasicHeaderValueParser.,
line 162 (ELEM_DELIMITER). 

Given the header: "Set-Cookie: testcookie=test; Expires=Wed, 03-Jul-2013 14:22:28 GMT; Path=/"


we end up with two HeaderElement instances: 
1. testcookie=test; Expires=Wed
2. 03-Jul-2013 14:22:28 GMT; Path=/ 

Now back from httpcore to httpclient:CookieSpecBase.parse(HeaderElement[], CookieOrigin),
line 93: 
This leads to BasicExpiresHandler.parse(SetCookie, String) being called with a value "Wed"
and to a MalformedCookieException. 

For the big picture: httpclient sessions that have to send cookies (e.g. for preventing redirect-loops)
will not work with servers sending this date format.
