<P>
<a name="method">
$r->method( [$meth] )
<blockquote>
The $r->method method will return the request method. It will be a
string such as ``GET'', ``HEAD'' or ``POST''. Passing an argument will
set the method, mainly used for internal redirects.
</blockquote>

<a name="method_number">
$r->method_number( [$num] )
<blockquote>
The $r->method_number method will return the request method
number. The method numbers are defined by the M_GET,
M_POST,... constants available from the Apache::Constants
module. Passing an argument will set the method_number, mainly used
for internal redirects and testing authorization restriction masks.
</blockquote>

<a name="bytes_sent">
$r->bytes_sent
<blockquote>
The number of bytes sent to the client, handy for logging, etc. 
</blockquote>

<a name="the_request">
$r->the_request
<blockquote>
The request line send by the client, handy for logging, etc. 
</blockquote>

<a name="proxyreq">
$r->proxyreq
<blockquote>
Returns true if the request is proxy http. Mainly used during the
filename translation stage of the request, which may be handled by a
PerlTransHandler.
</blockquote>

<a name="header_only">
$r->header_only
<blockquote>
Returns true if the client is asking for headers only, e.g. if the
request method was HEAD.
</blockquote>

<a name="protocol">
$r->protocol
<blockquote>
The $r->protocol method will return a string identifying the protocol
that the client speaks. Typical values will be ``HTTP/1.0'' or
``HTTP/1.1''.
</blockquote>

<a name="uri">
$r->uri( [$uri] )
<blockquote>
The $r->uri method will return the requested URI, optionally changing
it with the first argument.
</blockquote>

<a name="filename">
$r->filename( [$filename] )
<blockquote>
The $r->filename method will return the result of the URI --> filename
translation, optionally changing it with the first argument if you
happen to be doing the translation.
</blockquote>

<a name="path_info">
$r->path_info( [$path_info] )
<blockquote>
The $r->path_info method will return what is left in the path after
the URI --> filename translation, optionally changing it with the
first argument if you happen to be doing the translation.
</blockquote>

<a name="args">
$r->args
<blockquote>
The $r->args method will return the contents of the URI query
string. When called in a scalar context, the entire string is
returned. When called in a list context, a list of parsed key => value
pairs are returned, i.e. it can be used like this:
</blockquote>

<pre>
   $query = $r->args;
   %in    = $r->args;
</pre>
<%doc>
<a name="headers_in">
$r->headers_in 
The $r->headers_in method will return a %hash of client request headers. This can be used to initialize
a perl hash, or one could use the $r->header_in() method (described below) to retrieve a specific
header value directly. 
</%doc>

<a name="header_in">
$r->header_in( $header_name, [$value] )
<blockquote>
Return the value of a client header. Can be used like this: 
</blockquote>

<pre>
   $ct = $r->header_in("Content-type");
   $r->header_in($key, $val); #set the value of header '$key'
</pre>

<a name="content">
$r->content
<blockquote>
The $r->content method will return the entity body read from the
client, but only if the request content type is
application/x-www-form-urlencoded. When called in a scalar context,
the entire string is returned. When called in a list context, a list
of parsed key => value pairs are returned. *NOTE*: you can only ask
for this once, as the entire body is read from the client.
</blockquote>

<a name="read_client_block">
$r->read_client_block($buf, $bytes_to_read) 
Read from the entity body sent by the client. Example of use: 

   $r->read_client_block($buf, $r->header_in('Content-length'));

<a name="get_remote_host">
$r->get_remote_host= <% $r->get_remote_host %>
<blockquote>
Lookup the client's DNS hostname. If the configuration directive
HostNameLookups is set to off, this returns the dotted decimal
representation of the client's IP address instead. Might return undef
if the hostname is not known.
</blockquote>

<a name="get_remote_logname">
$r->get_remote_logname = NOT IMPLEMENTED BY MOD_PERL
<blockquote>
Lookup the remote user's system name. Might return undef if the remote
system is not running an RFC 1413 server or if the configuration
directive IdentityCheck is not turned on.
</blockquote>

More information about the client can be obtained from the
Apache::Connection object, as described below.
<P>
$c = $r->connection
<blockquote>
The $r->connection method will return a reference to the request
connection object (blessed into the Apache::Connection package). This
is really a conn_rec* in disguise. The following methods can be used
on the connection object:
</blockquote>

<a name="remote_host">
$c->remote_host
<blockquote>
If the configuration directive HostNameLookups is set to on: then the
first time $r->get_remote_host is called the server does a DNS lookup
to get the remote client's host name. The result is cached in
$c->remote_host then returned. If the server was unable to resolve the
remote client's host name this will be set to ``''. Subsequent calls
to $r->get_remote_host return this cached value.
<P>
If the configuration directive HostNameLookups is set to off: calls to
$r->get_remote_host return a string that contains the dotted decimal
representation of the remote client's IP address.  However this string
is not cached, and $c->remote_host is undefined. So, it's best to to
call $r->get_remote_host instead of directly accessing this variable.
</blockquote>

<a name="remote_ip">
$c->remote_ip
<blockquote>
The dotted decimal representation of the remote client's IP
address. This is set by then server when the connection record is
created so is always defined.
</blockquote>

<a name="local_addr">
$c->local_addr
<blockquote>
A packed SOCKADDR_IN in the same format as returned by Socket,
containing the port and address on the local host that the remote
client is connected to. This is set by the server when the connection
record is created so it is always defined.
</blockquote>

<a name="remote_addr">
$c->remote_addr
<blockquote>
A packed SOCKADDR_IN in the same format as returned by Socket,
containing the port and address on the remote host that the server is
connected to. This is set by the server when the connection record is
created so it is always defined.
<P>
Among other things, this can be used, together with $c->local_addr, to
perform RFC1413 ident lookups on the remote client even when the
configuration directive IdentityCheck is turned off.
<P>

Can be used like: 
<pre>
   use Net::Ident qw (lookupFromInAddr);
   ...
   my $remoteuser = lookupFromInAddr ($c->local_addr,
  $c->remote_addr, 2);
</pre>

Note that the lookupFromInAddr interface does not currently exist in
the Net::Ident module, but the author is planning on adding it soon.
</blockquote>

<a name="remote_logname">
$c->remote_logname
<blockquote>
If the configuration directive IdentityCheck is set to on: then the
first time $r->get_remote_logname is called the server does an RFC
1413 (ident) lookup to get the remote users system name. Generally for
UNI* systems this is their login. The result is cached in
$c->remote_logname then returned. Subsequent calls to
$r->get_remote_host return the cached value.
<P>
If the configuration directive IdentityCheck is set to off: then
$r->get_remote_logname does nothing and $c->remote_logname is always
undefined.
</blockquote>

<a name="user">
$c->user
<blockquote>
If an authentication check was successful, the authentication handler
caches the user name here.
</blockquote>

<a name="auth_type">
$c->auth_type
<blockquote>
Returns the authentication scheme that successfully authenticate
$c->user, if any.
</blockquote>

<a name="aborted">
$c->aborted
<blockquote>
Returns true if the client stopped talking to us.
</blockquote>

<h2>SERVER CONFIGURATION INFORMATION </h2>

The following methods are used to obtain information from server
configuration and access control files.

<a name="dir_config">
$r->dir_config( $key )
<blockquote>
Returns the value of a per-directory variable specified by the
PerlSetVar directive.
</blockquote>
<PRE>
   # <Location /foo/bar>
   # SetPerlVar  Key  Value
   # </Location>

   my $val = $r->dir_config('Key');

</PRE>

<a name="requires">
$r->requires
<blockquote>
Returns an array reference of hash references, containing information
related to the require directive.  This is normally used for access
control, see Apache for an example.
</blockquote>

<a name="auth_type">
$r->auth_type
<blockquote>
Returns a reference to the current value of the per directory
configuration directive AuthType.  Normally this would be set to Basic
to use the basic authentication scheme defined in RFC 1945, Hypertext
Transfer Protocol -- HTTP/1.0. However, you could set to something
else and implement your own authentication scheme.
</blockquote>

<a name="auth_name">
$r->auth_name
<blockquote>
Returns a reference to the current value of the per directory
configuration directive AuthName. The AuthName directive creates
protection realm within the server document space. To quote RFC 1945
``These realms allow the protected resources on a server to be
partitioned into a set of protection spaces, each with its own
authentication scheme and/or authorization database.'' The client uses
the root URL of the server to determine which authentication
credentials to send with each HTTP request.  These credentials are
tagged with the name of the authentication realm that created
them. Then during the authentication stage the server uses the current
authentication realm, from $r->auth_name, to determine which set of
credentials to authenticate.
</blockquote>

<a name="document_root">
$r->document_root
<blockquote>
Returns a reference to the current value of the per server
configuration directive DocumentRoot. To quote the Apache server
documentation, ``Unless matched by a directive like Alias, the server
appends the path from the requested URL to the document root to make
the path to the document.'' This same value is passed to CGI scripts
in the DOCUMENT_ROOT environment variable.
</blockquote>

<a name="allow_options">
$r->allow_options
<blockquote>
The $r->allow_options method can be used for checking if it is OK to
run a perl script. The Apache::Options module provides the constants
to check against.
</blockquote>

<pre>
   if(!($r->allow_options & OPT_EXECCGI)) {
 $r->log_reason("Options ExecCGI is off in this directory", 
    $filename);
   }
</pre>

$s = $r->server
<blockquote>
Return a reference to the server info object (blessed into the
Apache::Server package). This is really a server_rec* in disguise. The
following methods can be used on the server object:
</blockquote>

$s = Apache->server
<blockquote>
Same as above, but only available during server startup for use in
<Perl> sections, PerlScript or PerlModule.
<blockquote>

<a name="server_admin">
$s->server_admin
<blockquote>
Returns the mail address of the person responsible for this server.
</blockquote>

<a name="server_hostname">
$s->server_hostname
<blockquote>
Returns the hostname used by this server.
</blockquote>

<a name="port">
$s->port
<blockquote>
Returns the port that this servers listens too.
</blockquote>

<a name="is_virtual">
$s->is_virtual
<blockquote>
Returns true if this is a virtual server. 
</blockquote>

<a name="names">
$s->names
<blockquote>
Returns the wild-carded names for HostAlias servers. 
</blockquote>

<a name="warn">
$s->warn
<blockquote>
Alias for Apache::warn. 
</blockquote>

<a name="log_error">
$s->log_error
<blockquote>
Alias for Apache::log_error. 
</blockquote>
