Put URL and garbage in result from PHP

Just a follow-up on this.

Apparently "Content-Transfer-Encoding" is not a valid http header. (It may appear in parts of a multipart form).  So I should withdraw the claim that this is a bug in libUrl.

from rfc 2068:
-----------------------------------------------------------
19.4.4   No Content-Transfer-Encoding

HTTP does not use the Content-Transfer-Encoding (CTE) field of MIME.    
-------------------------------------------------------------

A quick check in older libUrl code shows that lineOffset("Transfer-Encoding:",<string>) is used to find the Transfer-Encoding header. That will pick up the Content-Transfer-Encoding header instead. That would explain what you're seeing.
