I am afraid the attachment got stripped away. Post it inline.

Hello Oleg,

I've tried "stdCookie.setExpiryDate(new

But my servlet gets -1 (when I get cookies from HttpServletRequest with

tried:

stdCookie.setExpiryDate(new java.util.Date(System.currentTimeMillis() +

But my servlet still receives -1 in MAX_AGE.

Finally, I'm trying to set the "ClientCookie.EXPIRES_ATTR" with the value

of

java.util.Date(System.currentTimeMillis() + 6)), but the value passed

to

setAttribute is expected to be a String, and I have a java.util.Date. How
can I make this conversion?

Thanks in advance,



Post a wire log of the session:

Also, try setting cookie version to version 1 to force the use of a RFC

Hello Oleg,

 


I?m trying to send cookies to a servlet with a simple app. Following the
tutorial:

 


HttpContext localContext = new BasicHttpContext();

CookieStore cookieStore  = new BasicCookieStore();

 
BasicClientCookie stdCookie = new BasicClientCookie("name", "value");

stdCookie.setVersion(1);
stdCookie.setDomain(".mycompany.com");
stdCookie.setPath("/");
stdCookie.setSecure(true);
 
// Set attributes EXACTLY as sent by the server 
stdCookie.setAttribute(ClientCookie.VERSION_ATTR, "1");

stdCookie.setAttribute(ClientCookie.DOMAIN_ATTR, ".mycompany.com");

 


 cookieStore.addCookie(stdCookie);

 localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

 


 HttpEntity entity = objHttp.execute(objPost, localContext).getEntity();

 

 


This does not work (at least for me). To work, you need to add:

 


stdCookie.setAttribute(ClientCookie.PATH, "/");
 
If I forget any of the ?set? statement, or any of the ?setAttribute?

statement, it does not work.
 
 
The question is: Why have we to set twice the components of the

?BasicClientCookie?, the first using ?stdCookie.set? and the second

using

?stdCookie.setAttribute??
 
And should I set ?ClientCookie.SECURE_ATTR? and

?ClientCookie.MAX_AGE_ATTR?

?



Joan

This is because some cookies set domain / path / port attributes

explicitly,

while some do not, in which case values of those attributes are derived

from

the properties of the origin server.

Consider the following example:

Set-Cookie: 
  stuff="very important"; path="/"; domain="myhost.mydomain.com";

version=1
Set-Cookie: 
  stuff="very important"; version=1


These two cookies are obviously different but they essentially represent

the

same piece of state information if sent in response to a request for
"http://myhost.mydomain.com/index.html";

 
 
And the second part: when the servlet receives this cookie, it is resent

to

another servlet using the same sequence of operations. But debugging,

one

can see that the cookie is not added to the cookieStore (the sentence
?cookieStore.addCookie(stdCookie);? does not add anything to

?cookieStore?).
A cookie does not get added to the cookie store only if it has expired.

Hope this helps

Oleg

 

Can you help me?
 
 
Thanks in advance,
 
Joan.

RE: QUESTION ABOUT COOKIES

2009-07-07 Thread Joan Balagueró Valls
Hello Oleg,

Thanks, after some tests this is exactly what it happens.

When I send this cookie to my servlet, I receive all its data correctly
except the "max-age" attribute, which is always -1.

I'm trying to set MAX_AGE with your API, and I'm getting crazy...

I've tried "stdCookie.setExpiryDate(new
java.util.Date(System.currentTimeMillis() + 6));  // Expires after 60
seconds

But my servlet gets -1 (when I get cookies from HttpServletRequest with
request.getCookies()).

I supposed that I had to set the same value for MAX_AGE attribute. Then I
tried:

stdCookie.setExpiryDate(new java.util.Date(System.currentTimeMillis() +
6));
stdCookie.setAttribute(ClientCookie.MAX_AGE_ATTR, "60");  // 60 seconds

But my servlet still receives -1 in MAX_AGE.

Finally, I'm trying to set the "ClientCookie.EXPIRES_ATTR" with the value of
java.util.Date(System.currentTimeMillis() + 6)), but the value passed to
setAttribute is expected to be a String, and I have a java.util.Date. How
can I make this conversion?

Thanks in advance,

Joan.

You don't. HttpClient automagically puts cookies into the HttpState
object that you use for executing the method. Don't do anything,
just let it happen. And make sure that the thread is using the
same HttpState objects for the followup requests. Do NOT create
HttpState objects for each request, just one for each thread or
session.

Hello,

Thanks for your response.

Now I know how to send a cookie just related to one thread. But how to

I was using : Cookie[] auxCookies = objHttp.getState().getCookies();

Now I know this is incorrect. I suppose that I must get cookies from the

You should have a separate HttpState object for each thread
instead of using the default HttpState object for all of them:
http://hc.apache.org/httpclient-3.x/apidocs/org/apache/commons/httpclient/Ht
tpClient.html#executeMethod(org.apache.commons.httpclient.HostConfiguration,

Check the domain and path attributes of your cookie.
Enable wire logging to see wether the cookie is sent or not.
http://hc.apache.org/httpclient-3.x/logging.html

hope that helps,

Hello Joan,

there is no need to shout.


The question is: doing this, am I setting this cookie for all threads or
just for the current thread that is executing this code?


For all threads.


Obviously, I want
to set this cookie just for the current thread, not for all. Is this
correct? And if not, how should I do it?


You should have a separate HttpState object for each thread
instead of using the default HttpState object for all of them:

And the following question is: this request is sent to another servlet, that
reads it. But if I examine the HttpServletRequest, I always get null for
cookies attribute. It’s like httpclient is not including the cookie in the
request I’m sending to the remote servlet.


Check the domain and path attributes of your cookie.
Enable wire logging to see wether the cookie is sent or not.

hope that helps,
