            Bug ID: 60424
           Summary: JMeter inserts 0x0D before 0x0A automatically (http
                    binary post data)
           Product: JMeter
           Version: 3.0
          Hardware: PC
                OS: Mac OS X 10.0
            Status: NEW
          Severity: normal
          Priority: P2
         Component: HTTP
          Assignee: issues@jmeter.apache.org
          Reporter: nminfo55-jmeter@yahoo.com
  Target Milestone: ---

Hi,
I like to work with JMeter and I like to get more and more experiences, too.
At the moment I want to do a load test with JMeter on http-protocol combined
with binary data. The application communicates via http Hessian protocol (a
binary data stream over http).

protocol: http binary content; Content-Type: x-application/hessian

Test-Setup:
- java application (app) with proxy setting: port 8888=20
- JMeter started with proxy setting: port 9000
- Fiddler started with sniffing at port 9000
- JMeter recorder with port =3D 8888

steps:
1. start Fiddler
2. start JMeter with proxy settings and prepare workbench with recorder
setting: port =3D 8888
3. start application=20
4. take an action "A"
5. play recorded request (without saving the project)
6. compare the post data of http-requests of step 4 and 5 with Fiddler

actual result:
- there are additional Bytes when JMeter plays the request
- especially: 0x0D is inserted before 0x0A
  i.a.: recorded part: 0x93, 0x0A, 0x6D
        played part  : 0x93, 0x0D, 0x0A, 0x6D
  i.a.: recorded part: 0x64, 0x0A, 0x6D
        played part  : 0x64, 0x0D, 0x0A, 0x6D
  i.a.: recorded part: 0x6E, 0x0A, 0x70
        played part  : 0x6E, 0x0D, 0x0A, 0x70


expected result:
- there is no modification of the binary stream

It seems that there is a difference between recording and replay of recorded
data. With that behaviour (post data modification) I can't use JMeter and I
have to look for other tools.

Regards,
Niko
PS: I can't attach files, because I use it at as a proof of concept at cust=
omer
side.
