function url_to_absolute in TMGMT Translator Smartling 8

Combine a base URL and a relative URL to produce a new absolute URL. The base URL is often the URL of a page, and the relative URL is a URL embedded on that page.

This function implements the "absolutize" algorithm from the RFC3986 specification for URLs.

This function supports multi-byte characters with the UTF-8 encoding, per the URL specification.

Parameters: baseUrl the absolute base URL.

url the relative URL to convert.

Return values: An absolute URL that combines parts of the base and relative URLs, or FALSE if the base URL is not absolute or if either URL cannot be parsed.
