NAME

ASP4::Server - Utility Methods

SYNOPSIS

  # Get the full disk path to /contact/form.asp:
  $Server->MapPath("/contact/form.asp");
  
  # Email someone:
  $Server->Mail(
    To      => 'jim@bob.com',
    From    => 'Joe Jangles <joe@jangles.net>',
    Subject => 'Test Email',
    Message => "Hello There!",
  );
  
  # Avoid XSS:
  <input type="text" name="foo" value="<%= $Server->HTMLEncode( $Form->{foo} ) %>" />
  
  # Proper URLs:
  <a href="foo.asp?bar=<%= $Server->URLEncode($Form->{bar}) %>">Click</a>

DESCRIPTION

The $Server object provides some utility methods that don't really fit anywhere else, but are still important.

PUBLIC METHODS

HTMLEncode( $str )

Performs a simple string substitution to sanitize $str for inclusion on HTML pages.

Removes the threat of cross-site-scripting (XSS).

Eg:

  <tag/>

Becomes:

  <tag/>

HTMLDecode( $str )

Does exactly the reverse of HTMLEncode.

Eg:

  <tag/>

Becomes:

  <tag/>

URLEncode( $str )

Converts a string for use within a URL.

eg:

  test@test.com

becomes:

  test%40test.com

URLDecode( $str )

Converts a url-encoded string to a normal string.

eg:

  test%40test.com

becomes:

  test@test.com

MapPath( $file )

Converts a relative path to a full disk path.

eg:

  /contact/form.asp

becomes:

  /var/www/mysite.com/htdocs/contact/form.asp

Mail( %args )

Sends email - uses Mail::Sendmail's sendmail(...) function.

RegisterCleanup( \&code, @args )

The supplied coderef will be executed with its arguments as the request enters its Cleanup phase.

See http://perl.apache.org/docs/2.0/user/handlers/http.html#PerlCleanupHandler for details.

Error( [%args] )

Calling <$Server-Error()>> without arguments will use the value of $@ and generate a ASP4::Error object from it, then pass it to the run(...) method of your <$Config-errors->error_handler>> for processing.

Please take a look at the documentation for ASP4::Error, ASP4::ErrorHandler and ASP4::ErrorHandler::Remote for details on how errors are handled.
