=head2 C<< Test::HTTP::LocalServer->spawn %ARGS >>
This spawns a new HTTP server. The server will stay running until
C<< $server->stop >> is called.
Valid arguments are:
=over 4
=item * html
scalar containing the page to be served
=item * file
filename containing the page to be served
=item * debug
Set to true to make the spawned server output debug information
=back
All served HTML will have the first %s replaced by the current location.

This returns the port of the current server. As new instances
will most likely run under a different port, this is convenient
if you need to compare results from two runs.

};

This returns the url where you can contact the server. This url
is valid until you call
C<< $server->stop >>
or
C<< $server->get_output >>
=cut
sub url {
my $url = $_[0]->{_server_url}->abs;
return $url->as_string;
};
=head2 C<< $server->creds_required >>
This returns a URL for a page that requires HTTP Basic-Auth. The
content returned is invariant and irrelevant; this method is for
testing credential-passing code. The username is 'luser' and the
password is 'fnord'. When these credentials are passed, the returned
status will be 200, otherwise it will be 401.
=cut
sub creds_required {
return $_[0]->{_server_url} . 'creds_required';
}
=head2 C<< $server->stop >>
This stops the server process by requesting a special
url.
=cut
sub stop {
get( $_[0]->{_server_url} . 'quit_server' );
undef $_[0]->{_server_url}
};
=head2 C<< $server->get_output >>
This stops the server by calling C<stop> and then returns the
output of the server process. This output will be a list of
all requests made to the server concatenated together
as a string.
=cut

my ($self) = @_;
