Karl Wright commented on HTTPCLIENT-1267:
-----------------------------------------
I built both httpcore.jar and httpclient.jar from their respective trunk areas,
and put them into place in ManifoldCF. Now I'm getting the following
exception, with the same code that runs without outputting any cookies:
>>>>>>

It seems like it is clearly looking for the cookie policy and finding something
it doesn't like. Hard to see how I could have caused this either, since my
code only sets the cookie store in the context:
>>>>>>
HttpContext context = new BasicHttpContext();
context.setAttribute(ClientContext.COOKIE_STORE,cookieStore);
response = httpClient.execute(executeMethod, context);
<<<<<<
There are too many changes between 4.2.2 and trunk for me to get sensible
results; I think I'm going to work off the 4.2.x branch in hopes of getting
something more stable.

> Key: HTTPCLIENT-1267
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1267
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpCookie
> Affects Versions: 4.2.2
> Reporter: Karl Wright
>
> In the port of ManifoldCF from commons-httpclient to httpcomponents, we
> discovered a problem or maybe a design flaw with how cookies are handled.
> What we're trying to do is to follow a certain series of html pages, and
> record the cookies after that is done, and use exactly those cookies for a
> subsequent series of pages. So I have code that looks something like this:
> {code}
> DefaultHttpClient httpClient = new DefaultHttpClient();
> ...
> CookieStore cs = new BasicCookieStore();
> cs.addCookie(...); // for each saved cookie
> httpClient.setCookieStore(cs);
> HttpGet httpget = new HttpGet(...);
> HttpResponse response = httpClient.execute(httpget);
> Cookie[] cookiesToSave = httpClient.getCookieStore().getCookies();
> [save the cookies aside]
> {code}
> What happens when I do this against a page that sets a cookie, is I get a
> perfectly reasonable cookie, and save it. For the next page, the code to add
> the cookie to the custom store then seems to work fine as well. But when I
> watch what is transmitted for the request (via header logging) I see no
> Cookie header being sent, and indeed the cookie seems to be lost.
> Similar logic was done with HttpState in commons-httpclient, and worked
> perfectly there against the same website.
> I have not yet tried the HttpContext approach for implementing this - I may
> try that while awaiting an answer to this ticket, but the above seems like it
> ought to work, according to the documentation.
