First, please note that many of these are possible just using
LWP::UserAgent.  Since \f(CW\*(C`WWW::Mechanize\*(C'\fR is a subclass of
LWP::UserAgent, whatever works on \f(CW\*(C`LWP::UserAgent\*(C'\fR should work
on \f(CW\*(C`WWW::Mechanize\*(C'\fR.  See the lwpcook man page included with
\&\s-1LWP\s0.

\&
\&    my $mech = WWW::Mechanize\->new( autocheck => 1 );
.Ve
.PP
The \f(CW\*(C`autocheck => 1\*(C'\fR tells Mechanize to die if any \s-1IO\s0 fails,
so you don't have to manually check.  It's easier that way.  If you
want to do your own error checking, leave it out.

.IX Subsection "Fetch a page"
.Vb 2
\&    $mech\->get( "http://search.cpan.org" );

.Ve
.PP
\&\f(CW\*(C`$mech\->content\*(C'\fR contains the raw \s-1HTML\s0 from the web page.  It
is not parsed or handled in any way, at least through the \f(CW\*(C`content\*(C'\fR
method.
.SS "Fetch a page into a file"
.IX Subsection "Fetch a page into a file"
Sometimes you want to dump your results directly into a file.  For
example, there's no reason to read a \s-1JPEG\s0 into memory if you're
only going to write it out immediately.  This can also help with
memory issues on large files.
.PP
.Vb 2
\&    $mech\->get( "http://www.cpan.org/src/stable.tar.gz",
\&                ":content_file" => "stable.tar.gz" );

.SS "Fetch a password-protected page"

Generally, just call \f(CW\*(C`credentials\*(C'\fR before fetching the page.
