2000-10-31 Hrvoje Niksic <hniksic@arsdigita.com>
* ftp.c (getftp): Ditto.
* http.c (gethttp): Rewind the stream when retrying from scratch.
2000-10-31 Hrvoje Niksic <hniksic@arsdigita.com>
* retr.c (retrieve_url): Use url_concat() to handle relative
redirections instead of /ad hoc/ code.
* url.c (url_concat): New function encapsulating weird
construct().
(urllen_http_hack): New function.
(construct): When constructing new URLs, recognize that `?' does
not form part of the file name in HTTP.
2000-10-13 Adrian Aichner <adrian@xemacs.org>
* retr.c: Add msec timing support for WINDOWS.
