=head1 Description

C<Apache2::RequestUtil> provides the L<Apache request
object|docs::2.0::api::Apache2::RequestRec> utilities API.





=head1 API




=head2 C<add_config>

Dynamically add Apache configuration at request processing runtime:

  $r->add_config($lines);
  $r->add_config($lines, $override);

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

=item arg1: C<$lines> (ARRAY ref)

An ARRAY reference containing configuration lines per element, without
the new line terminators.

=item opt arg2: C<$override> ( C<L<APR::Const status
constant|docs::2.0::api::APR::Const>> )

Which allow-override bits are set

Default value is:
C<L<Apache2::Const::OR_AUTHCFG|docs::2.0::api::Apache2::Const/C_Apache2__Const__OR_AUTHCFG_>>

=item ret: no return value

=item since: 2.0.00

=back

See also:
C<L<$s-E<gt>add_config|docs::2.0::api::Apache2::ServerUtil/C_add_config_>>

For example:

  use Apache2::ServerUtil ();
  $r->add_config(['require valid-user']);







=head2 C<as_string>

Dump the request object as a string

  $dump = $r->as_string();

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

=item ret: C<$dump> ( string )

=item since: 2.0.00

=back

Dumps various request and response headers (mainly useful for
debugging)




=head2 C<child_terminate>

Terminate the current worker process as soon as the current request is
over

  $r->child_terminate();

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

=item ret: no return value

=item since: 2.0.00

=back

This method is not supported in threaded MPMs



=head2 C<default_type>

Retrieve the value of the DefaultType directive for the current
request. If not set C<text/plain> is returned.

  $content_type = $r->default_type();

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

The current request

=item ret: C<$content_type> ( string )

The default type

=item since: 2.0.00

=back






=head2 C<dir_config>

C<$r-E<gt>dir_config()> provides an interface for the per-directory
variable specified by the C<PerlSetVar> and C<PerlAddVar> directives,
and also can be manipulated via the
C<L<APR::Table|docs::2.0::api::APR::Table>> methods.

  $table  = $r->dir_config();
  $value  = $r->dir_config($key);
  @values = $r->dir_config->get($key);
  $r->dir_config($key, $val);

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

=item opt arg2: C<$key> ( string )

Key string

=item opt arg3: C<$val> ( string )

Value string

=item ret: ...

Depends on the passed arguments, see further discussion

=item since: 2.0.00

=back

The keys are case-insensitive.

  $apr_table = $r->dir_config();

dir_config() called in a scalar context without the C<$key> argument
returns a I<HASH> reference blessed into the
C<L<APR::Table|docs::2.0::api::APR::Table>> class. This object can be
manipulated via the C<L<APR::Table|docs::2.0::api::APR::Table>>
methods. For available methods see
the C<L<APR::Table|docs::2.0::api::APR::Table>> manpage.

  $value = $r->dir_config($key);

If the C<$key> argument is passed in the scalar context only a single
value will be returned. Since the table preserves the insertion order,
if there is more than one value for the same key, the oldest value
assosiated with the desired key is returned. Calling in the scalar
context is also much faster, as it'll stop searching the table as soon
as the first match happens.

  @values = $r->dir_config->get($key);

To receive a list of values you must use C<get()> method from the
C<L<APR::Table|docs::2.0::api::APR::Table>> class.

  $r->dir_config($key => $val);

If the C<$key> and the C<$val> arguments are used, the set() operation
will happen: all existing values associated with the key C<$key> (and
the key itself) will be deleted and C<$value> will be placed instead.

  $r->dir_config($key => undef);

If C<$val> is I<undef> the unset() operation will happen: all existing
values associated with the key C<$key> (and the key itself) will be
deleted.







=head2 C<document_root>

Retrieve the document root for this server

  $docroot = $r->document_root();
  $docroot = $r->document_root($new_root);

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

The current request

=item opt arg1: C<$new_root>

Sets the document root to a new value B<only for the duration of the
current request>.

Note the L<limited functionality under threaded
MPMs|docs::2.0::api::Apache2::ServerRec/Limited_Functionality_under_Threaded_MPMs>.

=item ret: C<$docroot> ( string )

The document root

=item since: 2.0.00

=back








=head2 C<get_handlers>

Returns a reference to a list of handlers enabled for a given phase.

  $handlers_list = $r->get_handlers($hook_name);

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

=item arg1: C<$hook_name> ( string )

a string representing the phase to handle (e.g. C<PerlLogHandler>)

=item ret: C<$handlers_list> (ref to an ARRAY of CODE refs)

a list of handler subroutines CODE references

=item since: 2.0.00

=back

See also:
C<L<$s-E<gt>add_config|docs::2.0::api::Apache2::ServerUtil/C_get_handlers_>>

For example:

  my @handlers = @{ $r->get_handlers('PerlResponseHandler') || [] };







=head2 C<get_limit_req_body>

Return the limit on bytes in request msg body

  $limit = $r->get_limit_req_body();

=over 4

=item obj: C<$r>
( C<L<Apache2::RequestRec object|docs::2.0::api::Apache2::RequestRec>> )

The current request

=item ret: C<$limit> (integer)

=head2 C<get_server_name>

Get the current request's server name

  $server = $r->get_server_name();

=over 4

=item since: 2.0.00

=back

  use Apache2::RequestUtil ();
  my $hostport = join ':', $r->get_server_name, $r->get_server_port;





=head2 C<get_server_port>

Get the current server port

  $port = $r->get_server_port();

=over 4

For example:

  use Apache2::RequestUtil ();
  print Apache2::RequestUtil::get_status_line(400);

will print:

  400 Bad Request
