This is a text based file with one line per entry and each line consists of nine
|
|

## Example
|

|
## Fields
|
|
|
|
1. The ALPN id for the source origin
|
|
2. The hostname for the source origin
|
|
3. The port number for the source origin
|
|
4. The ALPN id for the destination host
|
|
5. The hostname for the destination host
|
|
6. The port number for the destination host
|
|
7. The expiration date and time of this entry within double quotes. The date format is "YYYYMMDD HH:MM:SS" and the time zone is GMT.

# TODO
|
|
|
|
- handle multiple response headers, when one of them says `clear` (should
|
|
override them all)
|
|
- using `Age:` value for caching age as per spec
|
|
- `CURLALTSVC_IMMEDIATELY` support
