 /* CURLOPT_RESOLVE address parsing test - to test the following defect fix:
 
- 1) if there is already existing host:port pair in the DNS cache and
- we call CURLOPT_RESOLVE, it should also replace addresses.
- for example, if there is "test.com:80" with address "1.1.1.1"
- and we called CURLOPT_RESOLVE with address "2.2.2.2", then DNS entry needs to
- reflect that.

- 2) when cached address is already there and close to expire, then by the
- time request is made, it can get expired.  This happens because, when
- we set address using CURLOPT_RESOLVE,
- it usually marks as permanent (by setting timestamp to zero). However,
- if address already exists
-in the cache, then it does not mark it, but just leaves it as it is.
- So we fixing this by timestamp to zero if address already exists too.
