Http Cookie Manager

[Pretterhofer, Guenter (ext.)]

Hi all,

I want to add some further details concerning my problems with the Http
Cookie Manager.

I did some testing with jmeter and with the tomcat session example that
comes with the software (SessionExample.java).
I'm using Tomcat 4.0.3 in "standalone" mode.


First I tested with two http requests only (please look at
NoCookieManager.jmx).
As expected I got the following output:

cookie = JSESSIONID=7EA7ABC2418EE7EC530B3FB4613A0280
Sampling url: http://localhost:9002/examples/servlet/SessionExample
    Header 1:  Content-Type: text/html
    Header 2:  Date: Mon, 08 Jul 2002 10:20:47 GMT
    Header 3:  Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
    Header 4:  Connection: close
    Header 5:  Set-Cookie:
JSESSIONID=6FFEF08B5A291C9010705B2F1FE3D8A8;Path=/examples
cookie = JSESSIONID=6FFEF08B5A291C9010705B2F1FE3D8A8
Sampling url: http://localhost:9002/examples/servlet/SessionExample
    Header 1:  Content-Type: text/html
    Header 2:  Date: Mon, 08 Jul 2002 10:20:47 GMT
    Header 3:  Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
    Header 4:  Connection: close
    Header 5:  Set-Cookie:
JSESSIONID=0EA73A6A409B837B61754D2D3DA510E5;Path=/examples
cookie = JSESSIONID=0EA73A6A409B837B61754D2D3DA510E5


Then I tested with two http requests and a Cookie Manager (CookieManager.jmx
attached):
I got the following output:
Sampling url: http://localhost:9002/examples/servlet/SessionExample
    Header 1:  Content-Type: text/html
    Header 2:  Date: Mon, 08 Jul 2002 10:27:27 GMT
    Header 3:  Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
    Header 4:  Connection: close
    Header 5:  Set-Cookie:
JSESSIONID=99F0F0DD074F580791F7128629A042FB;Path=/examples
cookie = JSESSIONID=99F0F0DD074F580791F7128629A042FB
Sampling url: http://localhost:9002/examples/servlet/SessionExample
    Header 1:  Content-Type: text/html
    Header 2:  Date: Mon, 08 Jul 2002 10:27:27 GMT
    Header 3:  Server: Apache Tomcat/4.0.3 (HTTP/1.1 Connector)
    Header 4:  Connection: close
cookie = null


To get the output above I added some lines in HttpSampler.java but I didn't
make any functional changes.

My question is: Why is the cookie "null" when requesting SessionExample the
second time when using the Cookie Manager?
I had expected to get the same Cookie value that I got for the first
request.


Thanks for your help,
G�nter

Betreff: Http Cookie Manager

Hi all,

hope all is well!

Maybe somebody can help me with the following problem?

In a thread group I defined a Http Cookie Manager and 2 Http Requests.
In each Http Request I call a servlet that gives me back a Cookie in the
Set-Cookie field in the http header.
I logged the Set-Cookie values that I get back from the server after every
Http Request.
For this purpose I logged the cookie value in readResponse() in
HttpSampler.java (conn.getHeaderField() ...).
I had hoped that the Set-Cookie value (JSESSIONID=...) would be the same in
both responses.

When I'm doing the same in the browser by calling the servlets via a 2 HTML
forms everything is fine.
Is there a possibility to ensure that I'm in the same Http session for 2 or
more Http Requests in Jmeter?

Thanks for your help!
G�nter
