/**
* soup_address_equal_by_name:
* @addr1: (type Soup.Address): a #SoupAddress with a resolved name
* @addr2: (type Soup.Address): another #SoupAddress with a resolved
* name
*
* Tests if @addr1 and @addr2 have the same "name". This method can be
* used with soup_address_hash_by_name() to create a #GHashTable that
* hashes on address "names".
*
* Comparing by name normally means comparing the addresses by their
* hostnames. But if the address was originally created using an IP
* address literal, then it will be compared by that instead.
*
* In particular, if "www.example.com" has the IP address 10.0.0.1,
* and @addr1 was created with the name "www.example.com" and @addr2
* was created with the name "10.0.0.1", then they will compare as
* unequal for purposes of soup_address_equal_by_name().
*
* This would be used to distinguish hosts in situations where
* different virtual hosts on the same IP address should be considered
* different. Eg, for purposes of HTTP authentication or cookies, two
* hosts with the same IP address but different names are considered
* to be different hosts.
*
* See also soup_address_equal_by_ip(), which compares by IP address
* rather than by name.
*
* Return value: whether or not @addr1 and @addr2 have the same name
*
* Since: 2.26
