Apache2::URI - Perl API for manipulating URIs
  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);
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.
"Apache2::URI" provides the
    following functions and methods:
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:
  - Assuming that:
    
      $r->get_server_name == "localhost";
  $r->get_server_port == 8001;
    The code:   $hostport = $r->construct_server();
    returns a string:   localhost:8001
    
- The following code sets the values explicitly:
    
      $hostport = $r->construct_server("my.example.com", 8888);
    and it returns a string:   my.example.com:8888
    
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:
  - 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. 
- 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
    
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 $uri.
Unescape URLs
  Apache2::URI::unescape_url($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";
