why cookies are removed when retrieving embedded resources in JMETER - cookies

I'm new to JMeter so forgive me if I'm asking the obvious. I am writing a performance test for a site protected by user password, where the authentication is passed as a token in the cookies.
I am able to extract the token and add it to the pages themselves, but when using "retrieve embedded resources" it seems like the cookies are being cleared. I have a single cookie manager at the top of the thread group and the token itself is being added by a beanshell postprocessor.
Any ideas ?
Gil.

I have never heard about cookies removal from the "embedded resources" request, looking into the View Results Tree listener the cookies are present on fresh JMeter 3.0 installation
If HTTP Cookie Manager is disabled or removed I don't see this "Cookie Data"
So my expectation is that you either misconfigured something or made a mistake in your Beanshell script.
By the way, you can "tell" JMeter to store cookies as JMeter Variables by adding CookieManager.save.cookies=true line to user.properties file. See Using the HTTP Cookie Manager in JMeter article for more detailed information.

How to extract Cookie Data in JMeter

I am new to JMeter and creating JMeter scripts on .Net Framework version 4.5.
I am facing a challenge or issue that how to extract/capture values like .ASPXAuth, AuthToken, Sesson ID generating on login into web application as Cookie Data but unable to use the same in the subsequent requests as there is no parameter available in Requests.
Actually, I need to extract the cookie data value from response header and to use it further in the subsequent requests. Please share the steps to do the same.
If you need to add cookies support to your JMeter script just add a HTTP Cookie Manager to your test plan.
The HTTP Cookie Manager automatically extracts the cookies from the Set-Cookie response header, checks their validity and adds them to the next request if domain and path of the HTTP Request samplers match the Cookie's domain and path.
So in the majority of cases it's sufficient to just add the HTTP Cookie Manager in order to get browser-like behaviour when it comes to cookies handling.
If you need to use the values of the cookies somewhere else, i.e. in a request parameter you can add the next line to user.properties file:
CookieManager.save.cookies=true
upon JMeter restart the incoming cookies values will be stored as JMeter Variables so you will be able to access the value of .ASPXAuth cookie as ${COOKIE_.ASPXAuth}, the value of AuthToken cookie as ${COOKIE_AuthToken}, etc.

Jmeter .ASPXAUTH cookie handling

Action:
Login page enter a username and password, after that .ASPXAUTH cookie set and these are maintain all the rest of the http request
The above said cookie (.ASPXAUTH) not stored in cookie section.
Please refer the screen shot
Response header set a .ASPXAUTH cookie
Once we pass the valid credentials request header (get method) maintain the same cookie throughout the session
Recorded the above login in jmeter while running the .ASPXAUTH cookie not set.
Let me know how can I handle this?
Try using cookie manager for managing the cookie automatically. This will take care of your cookies and it works in most of the cases.You can also check the below URL on how to build a basic web test plan.
https://jmeter.apache.org/usermanual/build-web-test-plan.html
Hope it helps.
Try the following steps:
Uncomment the next line in log4j2.xml file:
<Logger name="org.apache.jmeter.control" level="debug" />
This way you will have way more information regarding what's going on with the HTTP Cookie Manager under the hood
Play with "Cookie Policy" dropdown values, i.e. try netscape which is less restrictive than standard which is "too"-RFC 2109-compliant
Try adding the next line to user.properties file:
CookieManager.check.cookies=false
It will suppress JMeter's cookies validation logic.

How to generate a cookie and send it in a request in Jmeter

I am fairly new to Jmeter and hence having trouble figuring out the following:
I am testing a web service that needs a valid cookie to be sent in header. I have an endpoint url against which the userid and password validates. How do I validate the credentials against the url and extract the cookie for the user and send it in header for the request in Jmeter?
JMeter provides HTTP Cookie Manager which automatically handles cookies so in the majority of cases you don't need to do anything apart from adding the HTTP Cookie Manager to your Test Plan
However in some cases, i.e. in some CSRF implementations you need to add a request header holding previous response specific cookie value. In that case you should be acting like:
Add the next line to user.properties file (lives in JMeter's "bin" folder
CookieManager.save.cookies=true
Restart JMeter to pick the property up. The above setting "tells" JMeter to store cookie values as JMeter Variables prefixed by COOKIE_. So for example if you have cookie with the name of foo you will be able to access its value as ${COOKIE_foo}
Add HTTP Header Manager and set it up to send the desired header using ${COOKIE_foo} as a value (replace foo with your actual cookie name)

Can JMeter cookie manager override cookies set by the application?

I am testing an application that requires a user to authenticate, and then uses a cookie to track the user session. If authentication fails, a cookie is set that identifies the session as belonging to an unidentified user.
Unfortunately, authentication is via Kerberos or NTLM, which cannot be done in JMeter 2.8. My plan is therefore as follows:
Log into website with Internet Explorer.
Copy cookie that identifies session out of IE and into JMeter cookie manager as a user-defined cookie.
Use JMeter to test application
Essentially, this is session hijacking.
What I am observing is that (1) the JMeter cookie manager does not seem to be supplying the cookie to the application in the first request, (2) after the first request the application sends a different cookie back to JMeter, and (3) subsequent requests use the application-defined cookie, not the one I supplied.
So my questions are:
Is the approach described plausible, in theory at least?
Do application-defined cookies always override user-defined cookies?
Why might the cookie manager be not sending my user-defined cookie?
Thanks in advance.
Try using JMeter nightly build, it has been reported recently that it worked with NTLM after upgrade of httpclient libraries.
http://jmeter.apache.org/nightly.html
You approach seems really weird to me and I don't think it will work or even if it does be realistic.

JMeter Cookie Manager - not storing cookies?

Please VOTE TO CLOSE instead of downvoting. I can't delete the question now that there are answers for it.
I've been playing with JMeter a few days now and I'm starting to get into the steeper part of the learning curve it seems. I've added a login request (i had to put it in a Loop Controller in the Thread Group). I then have a cookie Manager followed by two requests that are made by the browser (according to fiddler) after logging in. These next two requests require a cookie though and they don't seem to be working right now. I've set the Cookie Manager to "compatibility" for Cookie Policy. Then I look at the view results tree and I see that the two requests after login are failing and in the Request tab I see "[no cookies]".
Rather perplexing. Here's a screenshot.
i've modified my login request a bit:
however the next request still fails with a "not logged in" and "forbidden" message:
Not sure as i don't have full test plan but your login request seems to have failed because you get a redirect from http to https in tree result.
As you can see in tree you have 2 samples inside
Login one with http then one i http.
I suggest if you are a beginer to read this :
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf
It will help you build easily yoyr test plan.
I you don't succeed with proxy then I suggest you remove loop controller and test with only one iteration to see what's happening.
You can click on sampler in tree result and select request tab.
Check that your login request is using https, it's in scheme of http sampler.
If it's a redirect that you cannot anticipate, then disable follow redirect and with a regexp post processor:
http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
extract the url from the redirect and submit it with login and password in next http sampler.

I had to learn a little bit more about the requests being made to the system in order for this to work. Instead of a call to www.server.com/login, i made a request to www.server.com/sessions.json and provided a json file with username and password. doint this set the cookie and the cookie manager took over. Then without modifying the other two requests, everything was honky dory.
Based on the images that you have posted, I found the error.
Cookie manager should be under the scope "Test plan". You have created a Cookie manager with the scope HTTP request.
Please leave the HTTP Cookie Manager with the standard settings. It should work.
