(Quote from The Open Group Base Specifications Issue 6 IEEE Std 1003.1, 2004
Edition)
The basename() function shall take the pathname pointed to by path and
return a pointer to the final component of the pathname, deleting any
trailing '/' characters.
If the string pointed to by path consists entirely of the '/' character,
basename() shall return a pointer to the string "/". If the string pointed
to by path is exactly "//", it is implementation-defined whether '/' or "//"
is returned.
If path is a null pointer or points to an empty string, basename() shall
return a pointer to the string ".".
The basename() function may modify the string pointed to by path, and may
return a pointer to static storage that may then be overwritten by a
subsequent call to basename().
The basename() function need not be reentrant. A function that is not
required to be reentrant is not required to be thread-safe.

think about how long we're willing to wait for more responses. */

purposes. For example, ARES_ENODATA is what we expect when there is
no IPv6 entry for a domain name, and that's not a reason to get more
aggressive in our timeouts for the other response. Other errors are
either a result of bad input (which should affect all parallel
requests), local or network conditions, non-definitive server
responses, or us cancelling the request. */
&& (status == ARES_SUCCESS || status == ARES_ENOTFOUND)) {
/* Right now, there can only be up to two parallel queries, so don't
bother handling any other cases. */
DEBUGASSERT(res->num_pending == 1);
/* It's possible that one of these parallel queries could succeed
quickly, but the other could always fail or timeout (when we're
talking to a pool of DNS servers that can only successfully resolve
IPv4 address, for example).
It's also possible that the other request could always just take
longer because it needs more time or only the second DNS server can
fulfill it successfully. But, to align with the philosophy of Happy
Eyeballs, we don't want to wait _too_ long or users will think
requests are slow when IPv6 lookups don't actually work (but IPv4 ones
do).
So, now that we have a usable answer (some IPv4 addresses, some IPv6
addresses, or "no such domain"), we start a timeout for the remaining
pending responses. Even though it is typical that this resolved
request came back quickly, that needn't be the case. It might be that
this completing request didn't get a result from the first DNS server
or even the first round of the whole DNS server pool. So it could
already be quite some time after we issued the DNS queries in the
first place. Without modifying c-ares, we can't know exactly where in
its retry cycle we are. We could guess based on how much time has
gone by, but it doesn't really matter. Happy Eyeballs tells us that,
given usable information in hand, we simply don't want to wait "too
much longer" after we get a result.
We simply wait an additional amount of time equal to the default
c-ares query timeout. That is enough time for a typical parallel
response to arrive without being "too long". Even on a network
where one of the two types of queries is failing or timing out
constantly, this will usually mean we wait a total of the default
c-ares timeout (5 seconds) plus the round trip time for the successful
request, which seems bearable. The downside is that c-ares might race
with us to issue one more retry just before we give up, but it seems
better to "waste" that request instead of trying to guess the perfect
timeout to prevent it. After all, we don't even know where in the
c-ares retry cycle each request is.

RECEIVING COOKIE INFORMATION
============================
struct CookieInfo *Curl_cookie_init(struct Curl_easy *data,
const char *file, struct CookieInfo *inc, bool newsession);
Inits a cookie struct to store data in a local file. This is always
called before any cookies are set.
struct Cookie *Curl_cookie_add(struct Curl_easy *data,
struct CookieInfo *c, bool httpheader, char *lineptr,
const char *domain, const char *path);
The 'lineptr' parameter is a full "Set-cookie:" line as
received from a server.
The function need to replace previously stored lines that this new
line supersedes.
It may remove lines that are expired.
It should return an indication of success/error.
SENDING COOKIE INFORMATION
==========================
struct Cookies *Curl_cookie_getlist(struct CookieInfo *cookie,
char *host, char *path, bool secure);
For a given host and path, return a linked list of cookies that
the client should send to the server if used now. The secure
boolean informs the cookie if a secure connection is achieved or
not.
It shall only return cookies that haven't expired.
Example set of cookies:
Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
domain=.fidelity.com; path=/ftgw; secure
Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
