NAME

       Apache2::URI - Perl API for manipulating URIs

Synopsis
	 use Apache2::URI ();

	 $hostport = $r->construct_server();
	 $hostport = $r->construct_server($hostname);
	 $hostport = $r->construct_server($hostname, $port);
	 $hostport = $r->construct_server($hostname, $port, $pool);

	 $url = $r->construct_url();
	 $url = $r->construct_url($rel_uri);
	 $url = $r->construct_url($rel_uri, $pool);

	 $parsed_uri = $r->parse_uri($uri);

	 $parsed_uri = $r->parsed_uri();

	 $url = join '%20', qw(one two three);
	 Apache2::URI::unescape_url($url);

Description
       While "APR::URI" provides a generic API to dissect, adjust and put together any given URI string, "Apache2::URI" provides an API specific
       to Apache, by taking the information directly from the $r object. Therefore when manipulating the URI of the current HTTP request usually
       methods from both classes are used.

API

       "Apache2::URI" provides the following functions and methods:

   "construct_server"
       Construct a string made of hostname and port

	 $hostport = $r->construct_server();
	 $hostport = $r->construct_server($hostname);
	 $hostport = $r->construct_server($hostname, $port);
	 $hostport = $r->construct_server($hostname, $port, $pool);

       obj: $r ( "Apache2::RequestRec object" )
	   The current request object

       opt arg1: $hostname ( string )
	   The hostname of the server.

	   If that argument is not passed, "$r->get_server_name" is used.

       opt arg2: $port ( string )
	   The port the server is running on.

	   If that argument is not passed, "$r->get_server_port" is used.

       opt arg3: $pool ( "APR::Pool object" )
	   The pool to allocate the string from.

	   If that argument is not passed, "$r->pool" is used.

       ret: $hostport ( string )
	   The server's hostport string

       since: 2.0.00

       Examples:

       o   Assuming that:

	     $r->get_server_name == "localhost";
	     $r->get_server_port == 8001;

	   The code:

	     $hostport = $r->construct_server();

	   returns a string:

	     localhost:8001

       o   The following code sets the values explicitly:

	     $hostport = $r->construct_server("my.example.com", 8888);

	   and it returns a string:

	     my.example.com:8888

   "construct_url"
       Build a fully qualified URL from the uri and information in the request rec:

	 $url = $r->construct_url();
	 $url = $r->construct_url($rel_uri);
	 $url = $r->construct_url($rel_uri, $pool);

       obj: $r ( "Apache2::RequestRec object" )
	   The current request object

       opt arg1: $rel_uri ( string )
	   The path to the requested file (it may include a concatenation of path, query and fragment components).

	   If that argument is not passed, "$r->uri" is used.

       opt arg2: $pool ( "APR::Pool object" )
	   The pool to allocate the URL from

	   If that argument is not passed, "$r->pool" is used.

       ret: $url ( string )
	   A fully qualified URL

       since: 2.0.00

       Examples:

       o   Assuming that the request was

	     http://localhost.localdomain:8529/test?args

	   The code:

	     my $url = $r->construct_url;

	   returns the string:

	     http://localhost.localdomain:8529/test

	   notice that the query (args) component is not in the string. You need to append it manually if it's needed.

       o   Assuming that the request was

	     http://localhost.localdomain:8529/test?args

	   The code:

	     my $rel_uri = "/foo/bar?tar";
	     my $url = $r->construct_url($rel_uri);

	   returns the string:

	     http://localhost.localdomain:8529/foo/bar?tar

   "parse_uri"
       Break apart URI (affecting the current request's uri components)

	 $r->parse_uri($uri);

       obj: $r ( "Apache2::RequestRec object" )
	   The current request object

       arg1: $uri ( string )
	   The uri to break apart

       ret: no return value
       warning:
	   This method has several side-effects explained below

       since: 2.0.00

       This method call has the following side-effects:

       1.  sets "$r->args" to the rest after '?' if such exists in the passed $uri, otherwise sets it to "undef".

       2.  sets "$r->uri" to the passed $uri without the "$r->args" part.

       3.  sets "$r->hostname" (if not set already) using the ("scheme://host:port") parts of the passed $uri.

   "parsed_uri"
       Get the current request's parsed uri object

	 my $uri = $r->parsed_uri();

       obj: $r ( "Apache2::RequestRec object" )
	   The current request object

       ret: $uri ( "APR::URI object" )
	   The parsed uri

       since: 2.0.00
	   This object is suitable for using with "APR::URI::rpath"

   "unescape_url"
       Unescape URLs

	 Apache2::URI::unescape_url($url);

       obj: $url ( string )
	   The URL to unescape

       ret: no return value
	   The argument $url is now unescaped

       since: 2.0.00

       Example:

	 my $url = join '%20', qw(one two three);
	 Apache2::URI::unescape_url($url);

       $url now contains the string:

	 "one two three";
