I'm trying to investigate the issue as I mentioned in the subject.
I login to the application and successfully able to land on the home page of my application through my JMeter code.
When I click on "user details" tab , I should be redirected 2 times.
Successfully able to redirect for the first time. For the second redirection I'm getting 500 error code instead of 302 again.
URL for "User details" is a plain URL, doesn't come with any need of correlation.
I have cookie manager with "standard"( tried all other options also on cookie manager)
I see that - cookie value SameSite=None; is also seen at request body along with other values only during the reply of my script(I do not see this in the recorded traffic/even if I cross verify using fiddler).
Would like to know if this can be a problematic. If so how can I remove this.
Try playing with Redirect Automatically and Follow Redirects boxes in the HTTP Request sampler
if it doesn't help - be aware that you can extract the redirect URL from the Location header using Regular Expression Extractor
If you think that the problem is with the cookie you can enable debug logging for the HTTP Cookie Manager by adding the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to see what's going on under the hood in jmeter.log file as it might be the case that the cookie is broken somehow (expired, wrong path, etc.)

For the purpose of my test, I need to send Cookie within the request like bellow.
If I try to do it with Header manager, cookies are ignored
I cant see them into the Request Headers where I need to see them.
Is there any way, how I can send Cokie into the reqest?
Note: Using Cokie managers is not working for me.
CookieManager.save.cookies=true
CookieManager.check.cookies=false
Are set up into the user.variables.
Using Jmeter 5.4.3
You're looking at wrong place, the cookies are displayed under Request -> Request Body tabs of the View Results Tree listener
So you might want to check your HTTP Cookie Manager setup, it might be the case it's "working". If it doesn't - there might be a problem with the cookies returned by your application, i.e. it's expired, domain mismatch, path mismatch, etc.
In that case you need to raise a bug for your application or change the implementation of the HTTP Cookie Manager to something less restrictive i.e. netscape
You can see what's going on under the hood with the cookies by increasing JMeter logging verbosity 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 re-run your test and take a look at jmeter.log file, you should see the incoming cookies and whether they're going to be added to the next request or not.
I am new to jmeter. I record my script using blazemeter chrome plugin. Now in login I am getting Cookies are required Cookies are disabled on your browser. please enable cookies and refresh this page I have set CookieManager.save.cookies=true but no luck .
As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
So if your page is using JavaScript in order to check user cookies there is no way to bypass this message, it means that you can just ignore it.
However if you cannot proceed further it means that JMeter doesn't send necessary Cookie header so make sure to add HTTP Cookie Manager to your test plan.
If you added the HTTP Cookie Manager but still seeing that the real browser sends cookies and JMeter doesn't (or sends partial) most probably it means that your server returns malformed or expired cookies and you need to raise a defect for your application.
And last but not the least, if you have to live with these malformed/broken cookies and still need to log in you can go for the following workarounds:
Change "Implementation" of the HTTP Cookie Manager to something less restrictive, i.e. netscape
Add the next line to user.properties file (lives in "bin" folder of your JMeter installation:
CookieManager.check.cookies=false
Increase JMeter logging verbosity for the HTTP Cookie Manager by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will be able to figure out what's wrong with the cookies
And last but not the least you can always manually extract cookies from the Set-Cookie response header using i.e. Regular Expression Extractor and again manually add them to the HTTP Cookie Manager or HTTP Header Manager
I am struggling with the cookies to clear after certain step. This is what I have in a sample test plan

I am getting a data from CSV file and then I have multiple cookies - which are location IDs which I need to pass for each row from CSV. I have tried using the Cookie Manager with option to clear iteration which works fine for next row from CSV but not to loop through cookie list defined in the user defined variable. I looked at this article
I have tried adding this code at the same level as the HTTP request but get an error
sampler.getCookieManager().clear() function should do the trick for you
Demo:
Given you're getting an NPE most probably something is wrong with your HTTP Cookie Manager configuration, you can try enabling debug logging for it to see if JMeter "complains" on anything and if it does - fix the HTTP Cookie Manager configuration accordingly.
In order to get extended debug information for the HTTP Cookie Manager add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control.CookieManager" level="debug" />
JMeter restart will be required to pick the property up.
Anyone looking for the answer it was quite simple in my case. I just had to add the blank Cookie Manager
Header Cookies
Earlier I had these filled with the values which was causing some issues.
Now I have added the JSR223 PreProcessor with this code and it worked fine
import org.apache.jmeter.protocol.http.control.CookieManager;
import org.apache.jmeter.protocol.http.control.Cookie;
Cookie newCookie;
CookieManager manager = sampler.getCookieManager();
location = vars.get("locationID_"+ vars.get("counter"))
Cookie myCookie = new Cookie("location_ID", location, google.com"/",false , 0);
manager.add(myCookie);
I build up very simple test plan.
Login: POST, a session cookie is returned.
Get the state: GET, a user state is returned.
Create a resource: POST, JSON body is supplied for the resource.
So my 'Test Plan' looks like:
Test Plan
Thread Group
HTTP Request Defaults
HTTP Cookie Manager
Login (HTTP Request Sampler: POST)
Get State (HTTP Request Sampler: GET)
Create Resource (HTTP Request Sampler: POST)
The cookie generated by 'Login' is added to 'Get State' correctly.
But 'Create Resource' has NO cookie. I changed their order but it doesn't help.
I used the default options firstly and changed some options but it also doesn't help.
Is it a bug of JMeter? or just POST http request is not able to have cookie?
Please give me any advice.
[SOLVED]
I noticed that it is related to the path, not the method.
You'd like to look at the domain of the cookie as well as the path.
I mean, the path and the domain of a cookie could be defined in the server side through Set-Cookie header.
Another solution is to set CookieManager.check.cookies=false in jmeter.properties usually sitting besides the jmeter startup script in bin.
JMeter for some reasons thinks that you can't set the path=/something in a cookie if you are on http:/somesite/somethingelse. That is the path has to match the path your currently on.
I've never seen a browser enforce this limitation if it actually exists. I've seen and written several sites that use this technique to set a secure cookie and then forward someone say to /admin.
I wish this option was at least in the GUI so I didn't have to change the properties file. I think BlazeMeter is smart enough to turn off checking where flood.io is not. If it were up to me I'd just remove the code that checks this entirely. Why make the load tester any harder then it needs to be.
I had this turned on in my Spring Boot server which was causing the issue with CookieManager in jMeter:
server.servlet.session.cookie.secure=true
Removing this made the cookies flow ! Of course this is for localhost. For Production you may need this turned on.
I am grabbing a webpage with WinHttp and the resulting page is the site's 404 file not found page. I know that the code works as I have tested it with other websites. The page in question is a normal http protocol and .html file.
What can I do?
You don't give a whole lot to go on. I'd probably start with a trace of the HTTP session from your WinHttp calls and compare it with a trace from a working browser-based session and see what's different. Could be anything from a cookie to a referer field to who-knows-what that the server might not like.
