Re: [Patch] Gallery export + HTTP Auth

[Fabian Steffen <fast neteye ch>]

Hi,

Maybe a bit a better solution. This time the patch uses a regex and not
substring-crap. The regex is used to determine whether it's an user+pass
containing-url or not and also splits it up.

BTW, this patch is not gallery-only specific, all connections using
http-basic-authentication via FormClient can benefit from it, if the url
was specified the right way (http://username:password example com).

cheers,
Fabian
