I added some new features so that now this should work:

	| client |
	(client := ZnClient new) 
		get: 'http://www.pharo-project.org'.
	self assert: client response isRedirect.
		enforceHttpSuccess: true;
		get: 'http://www.pharo-project.org'.
	self assert: client response isRedirect.
	client close

I think this will cover your use case, please let me know how it goes.

I discovered that I more ore less already had something that came close:

	| client response |
	client := ZnClient new url: 'http://www.pharo-project.org'.
	self assert: (client get; isSuccess).
		maxNumberOfRedirects: 0;
		url: 'http://www.pharo-project.org'.
	self should: [ client get ] raise: ZnTooManyRedirects.
	client close.
	response := [ ZnClient new beOneShot; maxNumberOfRedirects: 0; get: 'http://www.pharo-project.org'; response ]
		on: ZnTooManyRedirects do: [ :exception | exception resume ].
	self assert: response isRedirect 

Resuming the exception gave a true redirect response.

But that code is not very nice/handy, and it would not work when combined with enforceHttpSuccess: true.

These are new commits:

added new #followsRedirects boolean option to ZnClient

for an example see the ZnClientTests>>#testRedirectDontFollow
