Re: [xml] nanohttp: No redirects for http://www.domain.com

[Ralf Junker <ralfjunker gmx de>]

I could narrow the problem down to the fact that uri.c has indeed changed in an incompatible way. Consider 
this:

  uri = xmlParseURIRaw('http://www.google.com', 0);

After the call, in 2.7.5 uri->path contains an empty string. In previous versions it contained NULL, just 
like the other "empty" pieces.

I believe that this a bug in uri.c. It clearly results in the problem described in my initial message.
