For the http://axxerionfs.de site Location header is "AxxerionFMS/fs3_site.nsf/htmlViewHomepage/website_45B33F2E8E5BAA7EC125746C005E596B " when Zend_Http_Client used, it's redirecting to new path, but can't:

Zend_Uri_Exception:Path "/AxxerionFMS/fs3_site.nsf/htmlViewHomepage/website_45B33F2E8E5BAA7EC125746C005E596B   " is not a valid HTTP path

I'd like to suggest to change Zend_Http_Response::extractHeaders() as follows (i.e. simply adding a trim() or rtrim() call):

--- a/library/Zend/Http/Response.php
+++ b/library/Zend/Http/Response.php
