I want to pass browser automatically store cookies and manually added cookies in JMeter request.
enter image description here
Default cookie manager to use to get default cookies to browser create
into pet-type-3. HTTP Cookie Manager uses to add manually cookies to that request.
but that request also passes only default requests in browser creation.
How to pass these two types of cookies in this request.
Given you're providing valid cookies which match domain and path - they will be added along with the cookies coming in Set-Cookie response header
Demo:
as you can see by cookie foo with the value of bar has beed added to the "normal" cookies used by google
So I believe you just need to move your HTTP Cookie Manager to be direct child of the Thread Group as currently it's being applied to /pet-type-3 sampler only and in order to catch the cookies you call "browser" ones it need to be applied to all HTTP Request samplers.

I am attempting a performance test using JMeter.
The first controller performs a POST request to create a token en assign it to a variable.
The folloowing requests use this cookie to authenticate.
What I noticed is that after the first request with the cookies, the response contain a Set-Cookie header for each of the cookies.
Following requests use the old cookies (from the cookie manager) and the new cookies for the response.
I would like to overwrite the original cookie with the value of the new cookie.
I moved around the Cookie manager and edited the settings, but to no avail.
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.

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)

I'm setting a cookie in a response from my web service. The set-cookie header is coming through, and I can see the cookie in the network tab in Chrome, but the cookie isn't being stored. It doesn't show up in the resources->cookies tab, and the cookie isn't sent with subsequent requests. Nothing shows up in the JS console. I've also tried leaving the domain field off the cookie, but it still isn't stored.
Is there a way to debug the browser to understand why the cookie was rejected from being stored?
Turns out it had to do with the way I was making the request. I expected fetch() to work the same way as XHR requests. Setting credentials: 'include' on my fetch call resolved the problem. See 5.6.14 of the fetch spec
I don't really understand when session is created and per what entity it is created (per ip, per browser, per logged in user). I see in documentation that sessions by default is created per visitor - but what is visitor (browser or ip)?
What are HTTP sessions?
To display a webpage your browser sends an HTTP request to the server, the server sends back an HTTP response. Each time you click a link on website a new HTTP transacation takes place, i.e. it is not a connection that is persistant over time (like a phone call). Your communication with a website consists of many monolitic HTTP transactions (tens or hundres of phonecalls, each phonecall being a few words).
So how can the server remember information about a user, for instance that a user is logged in (ip addresses are not reliable)? The first time you visit a website, the server creates a random string, and in the HTTP response it asks the browser to create a so called HTTP cookie with that value. A cookie is really just a name (of the cookie) and a value. If you go to a simple session-enabled Django site, the server will ask your browser to set a cookie named 'sessionid' with such a random generated value.
The subsequent times your browser will make HTTP requests to that domain, it will include the cookie in the HTTP request.
The server saves these session ids (for django the default is to save in the database) and it saves them together with so called session variables. So based on the session id sent along with an HTTP request it can dig out previously set session variables as well as modify or add session variables. If you delete your cookies (ctrl+shift+delete in Firefox), you will realize that no website remembers you anymore (Gmail, Facebook, Django sites, etc.) and you have to log in again. Most browsers will allow you to disable cookies in general or for specific sites (for privacy reasons) but this means that you can not log into those websites.
Per browser, per window, per tab, per ip?
It is not possible to log into different GMail accounts within the same browser, not even from different windows. But it is possible to log in to one account with Firefox and another with Chrome. So the answer is: per browser. However, it is not always that simple. You can use different profiles in Firefox, and each can keep different cookies and thus you can log into different accounts simultaneously. There are also Firefox plugins for keeping multiple sessions, e.g. MultiFox.
The session all depends on which session cookie your browser sends in it's HTTP request.
Play around
To get the full understanding of what is going on, I recommend installing the FireBug and FireCookie plugins for Firefox. The above screenshots are taken from FireBug's net panel. FireCookie will give you an overview of when and which cookies are set when you visit a site, and will let you regulate which cookies are allowed.
If there is a server side error, and you have DEBUG=True, then the Django error message will show you information about the HTTP request, including the cookies sent
It's browser (not IP). A session is basically data stored on your server that is identified by a session id sent as a cookie to the browser. The browser will send the cookie back containing the session id on all subsequent requests either until the browser is closed or the cookie expires (depending on the expires value that is sent with the cookie header, which you can control from Django with set_expiry).
The server can also expire sessions by basically ignoring the (unexpired) cookie that the browser sends and requiring a new session to be started.
There is a great description on how sessions work here.
