=head1 NAME
Apache::*::Error - Exception classes for Apache::Request, Apache::Upload, Apache::Cookie::Jar and Apache::Cookie
=for testing
use Apache2;
use Apache::Upload;
use Apache::Cookie;
use APR::Error;
use APR::Pool;
$r = APR::Pool->new;
$req = Apache::Request->new($r);
$req->body_status(0);
$req->parse; # XXX sets up body table
$u = Apache::Upload->new($r, name => "foo", file => __FILE__);
$req->body->add($u);
$jar = Apache::Cookie::Jar->new($r);
$c = Apache::Cookie->new($r, name => "foo", value => "1");
$jar->cookies->add($c);
=head1 SYNOPSIS
=for example begin
$req = Apache::Request->new($r);
$jar = Apache::Cookie::Jar->new($r);
$req->args_status(1); # artificial error status = 1 for I<query-string> parser
$jar->status(2); # artificial error status = 2 for I<Cookie> header parser
eval { $req->parse };
ok $@->isa("Apache::Request::Error");
ok $@ == 1;
eval { @cookies = $jar->cookies };
ok $@->isa("Apache::Cookie::Jar::Error");
ok $@ == 2;
@cookies = $@->cookies; # same method does not fail on Error object
=for example end
=for example_testing
ok @cookies == 1;
=head1 DESCRIPTION
This manpage documents the Apache::*::Error classes provided by
the Apache::Request, Apache::Upload, and Apache::Cookie modules.
Error classes are all derived from APR::Error and the class
which first produced the error. Unlike the object that created it,
an Error object will not itself throw an error by calling its methods.
=head1 Apache::Request::Error
These exceptions are derived from APR::Error and Apache::Request,
and indicate that an error occurred during param parsing.
=for example begin
=for example end
=for example_testing
=head1 Apache::Upload::Error
These exceptions are derived from APR::Error and Apache::Upload,
and indicate that some Apache::Upload method failed (often caused
by a filesystem error).
=for example begin
=for example end
=for example_testing
=head1 Apache::Cookie::Jar::Error
These exceptions are derived from APR::Error and Apache::Cookie::Jar,
and indicate that the cookie parser failed to successfully parse the
incoming Cookie header.
=for example begin
=for example end
=for example_testing
=head1 Apache::Cookie::Error
These exceptions are derived from APR::Error and Apache::Cookie.
Their presence indicates that an Apache::Cookie method failed.
Typically they are caused by
1) attempting to bake(2) a non-compliant cookie,
2) attempting to set an unsupported cookie attribute.
=for example begin
=for example end
=for example_testing
