Description

In our Application we're facing problems using HttpClient 4.x (didn't have that problem with HttpClient 3.1). The HttpClient has problems parsing the Cookie's Expires-Attribute:

2011-04-08 10:14:21,647 [btpool0-0] WARN org.apache.http.client.protocol.ResponseProcessCookies - Invalid cookie header: "Set-Cookie: dfName=""; Expires=Thu, 01-Dec-94 16:00:00 GMT; Path=/appl/ebp". Unable to parse expires attribute: Thu

We are using Cookie-Policy RFC2109:

httpClient = new DefaultHttpClient(connectionManager);
httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY, CookiePolicy.RFC_2109);

The problems seems to be the JVM's default Locale, which is in our case de_AT and not en_US. See following Example:

[Java]
System.out.println("Locale=" + Locale.getDefault());
String[] datePatterns = new String[]

{ DateUtils.PATTERN_ASCTIME, DateUtils.PATTERN_RFC1036, DateUtils.PATTERN_RFC1123 }

;
for (String pattern : datePatterns) {
try

{ SimpleDateFormat dateFormat = new SimpleDateFormat(pattern); dateFormat.parse("Thu, 01-Dec-94 16:00:00 GMT"); }

catch (ParseException e)

{ System.out.println("Pattern '" + pattern + "' failed."); }

}
[/Java]

The output for me is following:

Locale=de_AT
Pattern 'EEE MMM d HH:mm:ss yyyy' failed.
Pattern 'EEEE, dd-MMM-yy HH:mm:ss zzz' failed.
Pattern 'EEE, dd MMM yyyy HH:mm:ss zzz' failed.

Setting the default Locale to US (Locale.setDefault(Locale.US)), the output changes:

Locale=en_US
Pattern 'EEE MMM d HH:mm:ss yyyy' failed.
Pattern 'EEE, dd MMM yyyy HH:mm:ss zzz' failed.

So the Date (Thu, 01-Dec-94 16:00:00 GMT) and the pattern (DateUtils.PATTERN_RFC1036: EEEE, dd-MMM-yy HH:mm:ss zzz) seem to be valid, just the Locale is not explicitly set for the SimpleDateFormat:

I hope I didn't waste your time and this is realy a bug.

Best regards,
