changing Content-Type for HTTP POST request

[Vladimir Lapacek <vl...@gmail.com>]

Hello,

I have the following problem with JMeter.

I am using GWT (Google Web Toolkit) java framework for building web
apps. GWT encapsulates ajax http calls, sending ajax requests via POST
to server.

Server always expects content-type: text/plain; charset=utf-8. That is
problem because JMeter's http sampler changes headers. Even if I have
correct setting for Content-type in the http request sampler node,
JMeter changes this and sends Content-Type:
application/x-www-form-urlencoded instead. As I said this is problem
with GWT ajax calls. Is there any way how to make JMeter not to change
this header? I used HTTP Request Manager Config element but with no
success.

As a workaround I manually changed the source code, edited
org.apache.jmeter.protocol.http.sampler.PostWriter and commented line
which changes the header. But isn't there any other way? And why is
JMeter changing the header?

Vladimir

Not at present - please file a Bugzilla enhancement request.

AFAIK, it's not using the header - it's setting the type directly,
because the type needs to be set for POST requests.
