/**
|

|
|
* getEffectiveTLDLength
|
||
|
|
*
|
||
|
|
* Finds the length of the effective TLD of a hostname. An effective TLD
|
||
|
|
* is the highest-level domain under which individual domains may be
|
||
|
|
* registered; it may therefore contain one or more dots. For example,
|
||
|
|
* the effective TLD for "www.bbc.co.uk" is "co.uk", because the .uk TLD
|
||
|
|
* does not allow the registration of domains at the second level ("bbc.uk"
|
||
|
|
* is forbidden). Similarly, the effective TLD of "developer.mozilla.com"
|
||
|
|
* is "com".
|
||
|
|
*
|
||
|
|
* The hostname will be normalized using nsIIDNService::normalize, which
|
||
|
|
* follows RFC 3454. getEffectiveTLDLength() will fail, generating an
|
||
|
|
* error, if the hostname contains characters that are invalid in URIs.
|
||
|
|
*
|
||
|
|
* @param aHostname The hostname to be analyzed, in UTF-8
|
||
|
|
*
|
||
|
|
* @returns the number of bytes that the longest identified effective TLD
|
||
|
|
* (TLD or TLD-like higher-level subdomain) occupies, not including
|
||
|
|
* the leading dot:
|
||
|
|
* bugzilla.mozilla.org -> org -> 3
|
||
|
|
* theregister.co.uk -> co.uk -> 5
|
||
|
|
* mysite.us -> us -> 2
|
||
|
|
*
|
||
|
|
* @throws NS_ERROR_UNEXPECTED
|
||
|
|
* or other error returned by nsIIDNService::normalize when
|
||
|
|
* aHostname is not UTF-8 or contains characters disallowed in URIs
