[Zope] Zope and chunked Transfer-Encoding problem

[Anton Zubenko]

Hello ppl,
Could anyone tell me whether Zope 2.5.1 supports Transfer-Encoding: chunked 
feauture of HTTP/1.1 for handling client request, such as sending a decent 
amount of data, e.g. file upload?
I get Bad Request error with response code 400.
I am pretty confident about the request correctness itself.

Thanks,
A.Z.
