For my application when I record , each HTTP request has required Headers that are maintained at individual HTTP Header Manager.
Now an Authentication token is also managed in the Header manager for every request after login. For multiple users I pass variable for this Authentication token. To make this happen I need to edit in every Header(or I do it opening jmx file in Notepad++ and then replacing all). But is there any way like using a global HTTP header manager that will override over Sample lever Headers.
As per Using JMeter's HTTP Header Manager article:
JMeter now supports multiple Header Managers.
The header entries are merged to form the list for the sampler. If an entry to be merged matches an existing header name, it replaces the previous entry, unless the entry value is empty in which case any existing entry is removed. This allows one to set up a default set of headers, and apply adjustments to particular samplers.
If you don't like the situation you can uncheck "Capture HTTP Headers" box in the HTTP(S) Test Script Recorder
If all headers are same throughout the script then you can remove all individual headers which are currently child of http request samplers and keep only one header manager outside of all request which will act as a global header manager and it will pass values to all requests

I cannot modify anything on user.properties to add next line CookieManager.save.cookies=true because I run my scripts from a remote machine in which I don't have access to.
I am able to capture the Cookie using a Regular Expression Extractor from RESPONSE HEADER in Login and save it in a variable 'Cookie_cp'. I tried adding 'Cookie_cp' on HTTP Cookie Manager and also tried adding it on HTTP Header Manager, but JMeter sends the cookie only on REQUEST BODY, but not the REQUEST HEADER.
Another issue is that 'Cookie_cp' is being captured from second step's RESPONSE HEADER and applied to third step, while I need this cookie to be applied only from Login to all other steps.
Any help please?
JMeter sends the cookie(s) in the Cookie header, not in the request body, if you're using View Results Tree listener to inspect the request and it shows the cookie in the "Request Body" tab it's kind of misleading.
In fact JMeter does send the cookie(s) in the Cookie header, you can double check it using a sniffer tool like Wireshark
If you want to send the cookie (or any other header) with all the requests starting from second one you can:
Put these requests under a Simple Controller
Add HTTP Cookie Manager (or HTTP Header Manager) at the same level as these requests
Both Cookie and Header manager obey JMeter Scoping Rules so the header(s) will be added to all Simple Controller's children
I've got a test fragment that makes a few requests, which work fine. I now want to add a new PUT request that uploads a file to a an azure storage account container. I currently get a 400 with an error that a mandatory header hasn't been included. After a little research it appears I need the 'x-ms-blob-type' header with a value of 'BlockBlob'.
This is where my issue lies. I've added an HTTP Header Manager to that particular request, but the header doesn't seem to get added. There is a Header Manager at the fragment level, that is used to apply generic headers to all requests, but this header manager is just for that request. I was expecting the 2 to be merged, but it looks like no headers are being applied to that particular request.
Your expectation is correct, HTTP Header Managers obey JMeter Scoping Rules and top-level headers are being recursively merged to the local HTTP Header Managers.
So try looking at Request -> Request Headers tab of the View Results Tree listener and see what headers are being sent
Additionally you can enable debug logging for JMeter's HTTP components by adding the next line to log4j2.xml file
<Logger name="org.apache.http" level="debug" />
and upon JMeter restart you should see the outgoing headers in jmeter.log file
You can also add header manager at request level as JMeter gives preference to the request level header manger even it is present at test plan level.
For reference see the attached snapshots.
Im writing script which have https request for uploading file. For this script I need to overwrite 'Content-Type' from global http header manager.
Is there any way to perform this in jmeter?
As per HTTP Header Manager documentation:
JMeter now supports multiple Header Managers. The header entries are merged to form the list for the sampler. If an entry to be merged matches an existing header name, it replaces the previous entry. This allows one to set up a default set of headers, and apply adjustments to particular samplers.
HTTP Header Manager respects JMeter Scoping Rules so if you need to override a header - add another HTTP Header Manager as a child of the Sampler which header you need to "override"
Demo:
I'm creating a record using post method from one user & verifying record with another user using Get method so for this I need 2 different tokens so what I did that I have used one Header Manager at the thread level & another Header Manager at HTTP-Request level now problem is that when I am running this Get API will get called & in the request header token of both user is getting passed. Can anyone know how to handle this?
If you need separate Header Manager per HTTP request, put each Header Manager under each HTTP request and not on thread level so it only affect the relevant request
HTTP Header Manager obeys JMeter Scoping Rules, so if you place it at the same level as Samplers - it will be applied to all Samplers.
If you add a HTTP Header Manager as a child of the Sampler - it will be applied to that Sampler only.
I recorded a web page using JMeter which has produced several samplers. Each of those samplers (http request) has a config HTTP Header Manager. Is it really necessary to have that for each sampler or can I just maintain one at the thread group level. Of course some of those Headers have referer header element and some don't.
You don't need one header per request, unless each request need a unique header.
You may not even need ONE at the threadgroup / test plan level, unless you are wanting to specify header information.
When you record, there is a checkbox in the HTTP Proxy to toggle capturing these.
It is enough one Header Manager per Thread. See documantation http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Header_Manager
