            Bug ID: 66234
           Summary: Chunk file upload with PUT method is failing due to
                    incorrect Content-Length auto calculation
           Product: JMeter
           Version: 5.4.3
          Hardware: PC
            Status: NEW
          Severity: major
          Priority: P2
         Component: HTTP
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: JMETER_5.5

Hi Team,

I am using "HTTP Request" with PUT method for chunk file upload at sFiles
{Salesforce share point}. (OS - Windows 10). FileToBeUploaded.pdf is the main
file 

$ ls -lrt File*
-rw-r--r-- 1 vikram 197121 12065018 Aug 23 15:51 FileToBeUploaded.pdf
-rw-r--r-- 1 vikram 197121  5773562 Aug 23 15:53 FileToBeUploaded_Chunks.pdf.ab
-rw-r--r-- 1 vikram 197121  6291456 Aug 23 15:53 FileToBeUploaded_Chunks.pdf.aa

For Chunk Upload
1. We have to divide a file to into equal parts and save it somewhere and
upload each of them separately on the same URL that you get after creating a
session.
2. Content-Length must be the total numbers of bytes of the file that you are
uploading in all upload requests of fragments.
3. Content-Range will be like:
0-{fragmentLength-1}/{totalNumberOfBytesOfFile}(same as content-length) and
from next fragment the Content-Range will be
{uploadedBytes}-{uploadedBytes+nextSetOfBytes-1}/{totalNumberOfBytesOfFile}

To follow this we should have valid Content-Length & Content-Range passed in
the request header. 

ISSUE: But Jmeter is calculating content-length automatically and not taking
the content-length defined in header manager. For chuck file uploads size in
bytes should be accurately set for Content-Length & Content-Range . But Jmeter
each time taking a new content-length as per it's auto calculation. 
Client Side Error: [HTTP 400]
{"error":{"code":"invalidRequest","message":"The Content-Range header length
does not match the provided number of bytes."}}

I searched on all articles on the internet but could not found any resolution
to control/override/hardcode Content-Length in request header. 
This issue must be there for all share point websites which are using PUT
method for chunk file upload. [Like Google Drive etc.]

Expected resolution: 
1. Way to control/override/hardcode/Configure Content-Length in "HTTP Request".
2. Addition of a new column under "Files Upload" along with File Path,
Parameter Name & MIME Type.

Your help is appreciated on this. Please do let me know for any kind of inputs
or information.
