After executing script, in Response Header: connection close message is getting displayed.(As this is the first HTTP Request)
I have recorded a script with the help of HTTP Test Script Recorder.
In the first request, there is no any field captured. But after executing script in Response Header:Connection Close message is displayed.
Response headers:

If you are totally sure that the connection doesn't need to be closed after the first request you can tick Use Keep-Alive box at the HTTP Request sampler level
This way JMeter will send Connection: keep-alive header along with the request hence the connection will not be closed after the request is done (which is more or less in line with what real browsers should be doing - they open a TCP stream and send requests over a single TCP connection)
However your situation might be different, I would recommend capturing the real headers sent by the real browser using browser developers tools or a sniffer tool like Wireshark and make sure JMeter sends the same headers (you can use HTTP Header Manager to add the headers of your choice to the request )
Add a HTTP Cookie Manager to your test plan.
Also, check this quick JMeter Recording guide for getting started

I am using JMeter 4.0 for recording & running performance tests. I am also fairly new to this tool and for the 1st time, I'm getting Error 400 Bad request for which all the tests are failing. I am recording a website through VPN & trying it to run the test the same way as I did before.
Can you please help me with this. I can provide additional screenshots and details as & when you say required.

As per 400 Bad Request description:
The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server could not understand the request due to invalid syntax.
The client should not repeat this request without modification.
So most probably you're sending malformed requests which server doesn't understand.
The only troubleshooting technique I can think of is recording requests which real browser sends using a sniffer tool like Fiddler or Wireshark and comparing them to what JMeter sends. The requests should be the same (apart from dynamic data which has to be correlated)
As soon as you amend your JMeter test plan to 100% match requests which are being sent by the real browser it should start working. Don't forget about Cookies and Headers.
As I know that if cors request comes with some extra headers set, first server needs to process it.
With CORS, the server must send the Access-Control-Allow-Headers header to allow uncommon request headers from the client.
Access-Control-Allow-Headers ... - Comma-delimited list of the supported request headers.
e.g suppose my pre-flight request is
OPTIONS /cors HTTP/1.1
Origin: http://api.bob.com
Access-Control-Request-Method: PUT
Access-Control-Request-Headers: X-Custom-Header
Host: api.alice.com
Accept-Language: en-US
Connection: keep-alive
User-Agent: Mozilla/5.0...
Then from server-side I will send response
Access-Control-Allow-Origin: http://api.bob.com
Access-Control-Allow-Methods: GET, POST, PUT
Access-Control-Allow-Headers: X-Custom-Header
Content-Type: text/html; charset=utf-8
My question is -
should I close the connection on server side while we send pre-flight response to client?
One more thing how can I cached pre-flight request for all other distinct subsequent requests?
Thanks
You could cache the OPTIONS request using the
Access-Control-Max-Age
header.
Attach it to the headers collection of the OPTIONS response.
But nevertheless an initial OPTIONS request by the user agent (browser) has to be made, you cannot avoid this.
But all further OPTIONS requests are cached and not issued to the server.
No need to close the connection.
Access-Control-Allow-Origin: http://hello-world.example
Access-Control-Max-Age: 3628800
Access-Control-Allow-Methods: PUT
as explained here, search for
could have the following headers specified
to get to the designated text section.
I have been trying to get a rather simple JMeter test up and running with cookies for days and having no luck at all. I have exhausted almost all SO threads with attempts to fix this, but no luck yet.
My test is simply to POST login username/password to a server, which returns a SAML token if successful. Then I resubmit that SAML token to my replying party site, which successfully responds with cookies in the headers.
However, every subsequent request does NOT pass along these cookies.
Here is the layout of my plan:
Thread Group
HTTP Request Default
HTTP Cookie Manager
HTTP Request - GET load login page
HTTP Request - POST user/pass to remote server and store SAML token
HTTP Request - POST Submit SAML token to Relying Party site (successfully returns cookies in response)
HTTP Request - GET View protected page (always send [no cookies])

I Have enabled these settings:
CookieManager.allow_variable_cookies=true
CookieManager.save.cookies=true
CookieManager.check.cookies=false

I also realise that some cookies are being set twice from the server, but this is out of my control. I hope that this is not the issue...
Pass the cookie variable in jMeter (you can access your ASP.NET_SessionId in this manner ${COOKIE_ASP.NET_SessionId}) to pass the cookie values to the HTTP Header Manager associated with the request.

My question is pretty simple. Although while searching over, I have not found a simple satisfying answer.
I am using Jquery ajax request to get the data from a server. Server
hosts a rest API that sets the Etag and Cach-control headers to the GET requests. The Server also sets CORS headers to allow the Etag.
The client of the Api is a browser web app. I am using Ajax request to call the Api. Here are the response headers from server after a simple GET request:
Status Code: 200 OK
Access-Control-Allow-Origin: *
Cache-Control: no-transform, max-age=86400
Connection: Keep-Alive
Content-Encoding: gzip
Content-Type: application/json
Date: Sun, 30 Aug 2015 13:23:41 GMT
Etag: "-783704964"
Keep-Alive: timeout=15, max=99
Server: Apache-Coyote/1.1
Transfer-Encoding: chunked
Vary: Accept-Encoding
access-control-allow-headers: X-Requested-With, Content-Type, Etag,Authorization
access-control-allow-methods: GET, POST, DELETE, PUT
All I want to know is:
Do I need to manually collect the Etag from response headers sent from the server and attach an if-no-match header to ajax request?OR the Browser sends it by-default in a conditional get request when it has an 'Etag'
I have done debugging over the network console in the browser and It
seems the browser is doing the conditional GET automatically and
sets the if-no-match header.
if it is right, Suppose, I created a new resource, and then I called the get request. It gives me the past cached data for the first time. But when I reload the page, It gives the updated one. So I am confused that, If the dataset on the server-side has changed and it sends a different Etag, Why doesn't the browser get an updated data set from the server unless I have to reload
Also in case of pagination. Suppose I have a URL /users?next=0. next is a query param where the value for the next changes for every new request. Since each response will get its own 'Etag'. Will the browser store the 'Etag' based on request or it just stores the lastest Etag of the previous get request, irrespective of the URL.
Well, I have somehow figured out the solution myself:
The browser sends the if-no-match header itself when it sees url had the e-tag header on a previous request. Browser saves the e-tag with respect to that URL, so it does not matter how many requests with different URLs happen.
Also, a trick to force the browser to fetch a conditional-get to check the e-tag:
Set the max-age header to the lowest (for me 60s works great)
once the cache expires, thebrowser will send a conditional-get to check if the expired cached resource is valid. If the if-no-match header matches with e-tag. The server sends the response back with 304: Not-Modified header. This means the expired cached resource is valid and can be used.
I built a WebSocket server using WebSocket-Node and the client is an Arduino with an Ethernet shield using the library WebsocketClient from krohling.
The first issue I had was that even the example from the WebsocketClient library didn't return a response from the echo.websocket.org server.
Since the Arduino's Serial monitor didn't give me errors, I added a Serial.print on the handshake section of the library's code to debug the error and I got the following:
HTTP/1.1 400 Bad Request
Server: Kaazing Gateway
Date: Tue, 07 May 2013 05:11:21 GMT
Access-Control-Allow-Origin: ArduinoWebSocketClient
Access-Control-Allow-Credentials: true
Access-Control-Allow-Headers: content-type
Access-Control-Allow-Headers: authorization
Access-Control-Allow-Headers: x-websocket-extensions
Access-Control-Allow-Headers: x-websocket-version
Access-Control-Allow-Headers: x-websocket-protocol
Content-Type: text/html
Content-Length: 63
Connection: Keep-Alive
Then, I tested it with the WebSocket-Node server I created and got the following on the Serial monitor:
HTTP/1.1 400 Bad Request
Connection: close
X-WebSocket-Reject-Reason: Client must provide a value for Sec-WebSocket-Key.
Am I doing something wrong or does the WebsocketClient library need to be updated?
I haven't been lucky to find a better/newer Arduino Websocket client library. Does anyone know about one I could use?
Thanks a lot!
