I want to create a small java application to copy some wiki content from one server to another. The API is based on the XML-RPC.

Basically I have three methods, login, getPage and putPage. I use Apache HttpClient 3.x and managed to use login to login successfully and getPage to get a page from the old wiki correctly.

Authentication is handled with cookies: I log into the new wiki and some cookies are set on the corresponding httpclient. The doku tells me that one of those cookies is used for authentification.

Then I execute putPage with another POST method on the same httpclient and the server responds with a authentication failure message.

The code sequence goes like this (very reduced):

HttpClient client = new HttpClient();
PostMethod postLogin = createNewPostMethod("login", "user", "pw");
client.executeMethod(postLogin);
// Now I'm logged in and the client definitly has stored the cookies
PostMethod postPutPage = createNewPostMethod("putPage", getPage());
client.executeMethod(postPutPage);  // the server won't let me put the page

Should it work like that or do I have to add the cookies manually to the second post method and, if yes, how?

Edit / Solution

With the help of the answers to this question I was able to identify and solve the problem, which was outside of the usage of httpclient. At the end it was a configuration issue on the target wiki side. The answers here helped me to ask the right questions in another forum.

    Cookies are handled by HTTPClient by default. You shouldn’t have to do anything to have cookies work properly.

    Edit for Apache HTTP Client:

    Apache HTTP Client behaves the same 🙂
