| 5 | # Client features
|
| 6 | #
|
| 7 | # - SSL, for HTTPS
|
| 8 | # - Connection: Keep-Alive, for latency
|
| 9 | # - Timeouts, for robustness
|
| 10 | # - Client side redirects
|
| 11 | # - Sending arbitrary headers, for auth
|
| 12 | # - Encoding: URL encoding, multi-part/MIME
|
| 13 | # - It would be nice to offload this encoding, similar to how CGI v2 offloads
|
| 14 | # parsing
|
| 15 | # - Large streaming uploasd and downloads - this might need to be a separate
|
| 16 | # request, e.g. to the wwup process
|
| 17 | #
|
| 18 | # Probably don't care about:
|
| 19 | # - HTTP Cache - we might have a different mechanism - this is very complex and
|
| 20 | # "best effort"
|
| 21 | # - or there can be local cache of the "Oils SQL Waist"
|
| 22 | # - Cookies? Not sure
|
| 23 | #
|
| 24 | # Not sure:
|
| 25 | # - Proxy support
