How to pass dynamic cookie in jmeter? - jmeter

I have added HTTP Cookie Manager and HTTP Authorization Manager in Test Plan. When run the script following response message I have received
Response code: 401
Response message: UNAUTHORIZED
{"message":"Access is Denied","severity":"danger"}
This is my cookie
_ga=###; _gid=###; _gat=#; accessInfo={###}; userInfo={###}; 574ae166fc51fa5bdbd8beef725e77d7={###}; session=.###
But when run script only partial session is pass from my above cookie data through header request.
I also tried using regular expression but not getting response.
Can anyone suggest me how and where I can pass my cookies dynamically?

If the next request doesn't have all the cookies which you can see in the previous response Set-Cookie header most probably it indicates problem with the cookies.
You can check what exactly JMeter does with cookies by enabling debug logging for the HTTP Cookie Manager, in order to do this add the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation:
<Logger name="org.apache.jmeter.protocol.http.control.CookieManager" level="debug" />
JMeter restart will be required to pick up the change.
Other things to try:
Turn off JMeter built-in checks for cookies. In order to do this add the next line to user.properties file
CookieManager.check.cookies=false
Play with "Implementation" drop-down value, i.e. try choosing less restrictive implementation, for example netscape

Jmeter cookie manager not renewing cookie with each loop

I am fairly new to jmeter and currently I am using jmeter to create a test plan with Prometheus plugin, we have various endpoints that needs to be probed, our application use a cookie that refreshes every day so the cookie value changes likewise. Once the jmeter runs on the host, it gives 200 response code but after a day, when the cookie refreshes, we start seeing 401s for all the endpoints, my guess is the cookie is not being generated properly. I am using HTTP cookie manager in the jmeter which supposedly gets the cookie automatically, and I also have selected clear cookie each iteration but it doesn’t seem to work.Please help.
HTTP Cookie Manager does really clear cookies but it applies only to Thread Group iteration, other Logic Controllers like Loop Controller or While Controller won't trigger cookies renewal.
You can check what exactly is happening by enabling debug logging for the HTTP Cookie Manager: add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
and upon JMeter restart the jmeter.log file will contain information regarding incoming and outgoing cookies.
It's also possible to force clear cookies, it can be done by adding a JSR223 PreProcessor as a child of the very first HTTP Request sampler and putting the following code into "Script" area:
sampler.getCookieManager().clear()

Jmeter Not Able to send Cookies In Quotes " ", Netscape doesn't work

I am having this strange problem where i need to send multiple cookies as part of my Jmeter Script HTTP request.
Following are my cookies which i get in my response:
Set-Cookie:
AWSALB=CookieValue
AWSALBCORS=CookieValue
Pega-RULES="CookieValue"
If I select Standard Mechanism in Cookie manager it identifies all cookies, but doesn't send Pega-RULES cookie in Quotes " " in the next request and the scripts fail.
If i select Netscape in Cookie Manager it identifies only Pega-RULES Cookie and sends the cookie in "" but Doesn't recognize AWS Cookies and doesn't send AWS Cookies in next cookies, again the script fails.
Please help me find a solution.
Many Thanks,
Suhail
You can try adding the next line to user.properties file:
CookieManager.check.cookies=false
so if there is a problem with any of your cookies - JMeter will not "discard" it and send it with the next request even if it's expired or domain doesn't match, etc.
To get more insight regarding what's going on with the cookies under the hood you can enable debug logging for the HTTP Cookie Manager by adding the next line to log4j2.xml file
Also be aware that you can always extract any cookie from the Set-Cookie response header using i.e. Regular Expression Extractor and add them either to HTTP Header Manager or to the HTTP Cookie Manager as user-defined cookie
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />

JMeter - I need to pass a parameter called "Cookie" in the request header

I am using apache jmeter 5.2.1 with Java 8 to perform the performance test in a JSF application.
I need to send in the header of an HTTP request a parameter called "Cookie" according to the example below:
I've tried several things but none work.
I have already used the HttpHeaderManager resource but apparently the word "Cookie" is a JMeter reserved word so I can't create a parameter in the Header with the name "Cookie".
If I create a parameter in HttpHeaderManager with any name it is appended to the request header, but if I create with the name "Cookie" which is the name I need to use JMeter simply ignore it and do not add it to the request header .
I saw many posts indicating that I used the following code snippet:
CookieManager manager = sampler.getCookieManager();
Cookie cookie = new Cookie("JSESSIONID",vars.get("jSessionId"),"${serveraddress}",false,0);
manager.add(cookie);
I've tested it but it doesn't work either, it returns the following error whenever I try to use it:
I also have an Http Cookie Manager but its value is sent in the request body and not in the header.
I also tried to use the Http Autorization Manager as I saw in some posts but it only works when the login is done at a prompt in the browser.
Can someone help me?
Just add a HTTP Cookie Manager to your Test Plan and it will automatically "manage" cookies for you (the HTTP Request samplers must be in the HTTP Cookie Manager's scope)
You can double check that JMeter sends correct Cookie header using a 3rd-party sniffer tool like Wireshark or Fiddler
If you added the HTTP Cookie Manager but JMeter still doesn't send the JSESSIONID cookie it might be the case there is a problem with the cookie itself, i.e. it doesn't match domain/path or expired or your HTTP Request sampler configuration is not correct.
If you absolutely sure that your application behaves as expected you can configure JMeter to be less restrictive by:
Choosing a more "relaxed" cookie policy, i.e. netscape
Adding the next line to user.properties file:
CookieManager.check.cookies=false
You can also add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will get comprehensive information of the Cookie Manager's behaviour in the jmeter.log file

JMeter:How to post cookie data in Request Header

I can able to get the "set-cookie" data by regular expression extractor/ by setting it in the JMeter user properties file but I can't get the following cookie data to use it in the "Request Header" as like defining user-agent.
Cookie info displayed in the browser as follows:
connection keep-alive
User-Agent xxxxxx
Cookie _ga=GA1.2.1710658689.1468689932
Where do I find the "_ga" Value such that I will use it.
What is the regular expression for it.
Kindly help me it is blocking.
The easiest way of automatically handling cookies is using HTTP Cookie Manager. If for some reason you need to use cookie value somewhere else - you can extract it as follows:
Add the next line to user.properties file (lives in JMeter's "bin" folder)
CookieManager.save.cookies=true
Restart JMeter to pick the property change up
Add HTTP Cookie Manager to your Test Plan
Refer extracted cookies as ${COOKIE_YOUR_COOKIE_NAME_HERE} where required i.e. ${Cookie__ga} in your case
User-Agent and any other headers can be specified via HTTP Header Manager.
In my scenario it got worked without posting the above mentioned cookie. It worked by posting the set-cookie info and Location value in the header manager. Thanks!

jmeter HTTP response does not show cookies or header response

I am new to jmeter. I have setup up HTTP Request sampler to send GET request to google.com. The response I get is 200. But I could not find the response header where it shows the cookies in the response. I want to use that cookie value for my next request.
You need to look into View Results Tree listener, Set-Cookie header will present in "Sampler Result" tab:
HTTP Cookie Manager should handle cookies automatically. Just in case if you need cookies to be store as JMeter Variables you can set the following property:
CookieManager.save.cookies=true
which can be done in 2 ways:
Pass it to JMeter startup script via -J command line argument as:
jmeter -JCookieManager.save.cookies=true
Add aforementioned CookieManager.save.cookies=true line to user.properties file (located in "bin" folder of your JMeter installation) to make the change permanent. Remember, JMeter restart is required to pick the property up.
This way you will be able to access i.e. NID cookie value as ${COOKIE_NID} where required
See Using the HTTP Cookie Manager in JMeter guide for more information on using HTTP Cookie manager
To handle the cookies automatically, Add HTTP Cookie Manager to the test plan by navigating to Test plan -> Add -> Config Element -> HTTP Cookie Manager.
And don’t test the applications which you don't own or have permission to test.
