# Tesses.WebServer
|
||||
|
||||
A TcpListener HTTP Server
|
||||
|
||||
Currently Supports
|
||||
- GET+HEAD+POST Requests
|
||||
- Seekable Video Files (Using Range)
|
||||
- Can Send Json To Client with helper function (uses Newtonsoft.Json)
|
||||
- Cors Header
|
||||
|
||||
# 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
|
||||
- Basic Auth Class
|
||||
|
||||
# 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"))
