Converts RFC1123 string that looks like this: Mon, 29 Mar 2021
15:37:13 GMT to a UNIX timestamp. See parsehttpdatetime.c.
ParseUrl(str) → URL
Parses URL, returning object having the following fields: scheme,
user, pass, host, port, path, params, fragment. This parser is
charset agnostic. Percent encoded bytes are decoded for all
fields. Returned values might contain things like NUL characters,
spaces, control codes, and non-canonical encodings. Absent can be
discerned from empty by checking if the pointer is set. There's no
failure condition for this routine. This is a permissive parser.
This doesn't normalize path segments like `.` or `..` so use
IsAcceptablePath() to check for those. No restrictions are imposed
beyond that which is strictly necessary for parsing. All the data
that is provided will be consumed to the one of the fields. Strict
conformance is enforced on some fields more than others, like
scheme, since it's the most non-deterministically defined field of
them all. Please note this is a URL parser, not a URI parser.
Which means we support everything everything the URI spec says we
should do except for the things we won't do, like tokenizing path
segments into an array and then nesting another array beneath each
of those for storing semicolon parameters. So this parser won't
make SIP easy. What it can do is parse HTTP URLs and most URIs
like data:opaque, better in fact than most things which claim to
be URI parsers.
ParseUrl(url:str[, flags:int]) → URL
Parses URL.
An object containing the following fields is returned:
- `scheme` is a string, e.g. `"http"`
- `user` is the username string, or nil if absent
- `pass` is the password string, or nil if absent
- `host` is the hostname string, or nil if `url` was a path
- `port` is the port string, or nil if absent
- `path` is the path string, or nil if absent
- `params` is the URL paramaters, e.g. `/?a=b&c` would be
represented as the data structure `{{"a", "b"}, {"c"}, ...}`
- `fragment` is the stuff after the `#` character
`flags` may have:
- `kUrlPlus` to turn `+` into space
- `kUrlLatin1` to transcode ISO-8859-1 input into UTF-8

IsAcceptablePath(str) → bool
Returns true if path doesn't contain ".", ".." or "//" segments
