@ -7,16 +7,17 @@ Currently Supports
- Seekable Video Files (Using Range)
- Can Send Json To Client with helper function (uses Newtonsoft.Json)
- Cors Header
- HTTPS Support (At least I think It will work)
# Classes To Make It Easier
- Static Website Class (Can pass in other class (instead of 404 when file doesnt exist) can choose other names other than index.html, index.htm, default.html, default.htm)
- 404 Not Found Class
- Mount class (So you could use Api)
# Comming Soon Hopefully
- Mount class (So you could use Multiple Apis, And Static Sites If you want)
- Basic Auth Class
- Route Class (Just like dajuric/simple-http)
- Host Name Class (like Mount Class but is used for hostnames/ip addresses like tesses.cf, 192.168.0.142, demilovato.com, ebay.com)
# Might Happen But not sure
- WebDav Class
> Note: Range code and POST code is not mine its a modified version of the code from ( [dajuric/simple-http](https://github.com/dajuric/simple-http/blob/master/Source/SimpleHTTP/Extensions/Response/ResponseExtensions.PartialStream.cs "dajuric/simple-http"))
