When using httpclient4 implement to upload files, the content-type parameter cannot be set correctly.

[asfimport]

zooltech (Bug 65310):
There is a default content-type parameter in HTTP Manager coomponent.

The upload sampler(Http Request):
In the request header sent by java implement, the value of content-type is correct.
In the request header sent by httpclient4 implement, the value of content-type is the default value defined by HTTP Manager, not the correct value.

See the attachment for details.

@zooltech, could you test the next nightly or build from trunk and report back, whether it fixes this issue?

commit 7ac71f1

Don't let users override content-type header when using multipart/form-data

The content-type header will contain the boundary from the multiparts. That
value can't be guessed by the user and using the original given content-type
will very likely be wrong.

Apart from that reason, the Java implementation of HTTPSampler will use
the generated content-type anyway and therefore this patch will make the
two implementations behave consistently.

Closed, as no feedback probably means, it works.
