This module escapes or unescapes "unsafe" characters within a URL string. Unsafe characters in URLs are described by RFC 1738. Before you form URI::URL objects and use that class's methods, you should make sure your strings are properly escaped. This module does not create its own objects; it exports the following functions:
This module creates URL objects that store all the elements of a URL.
These objects are used by the
This method creates a new URI::URL object with the URL given as the first parameter. An optional base URL can be specified as the second parameter and is useful for generating an absolute URL from a relative URL.$url = new URI::URL($url_string [, $base_url])
The following list describes the methods for the URI::URL class:
