Using Java `long` on Android works again, but they are not fully compatible with Nit's `Int`. Java's `long` are on 64 bits, and Nit's `Int` on 32 bit under ARM. There may be data loss.

Nitcorn is a Web server framework to create sever-side applications in Nit. It is currently used at http://tnitter.xymus.net/ and http://vps.xymus.net/nit/index.html The README files is missing and will be added soon.

* GET and POST support (for small uploads)
* Virtual hosts and routes
* Sessions
* Reading cookies
* Adding virtual hosts (and interfaces) on the fly
* Adding/removing route on the fly
* Play well with existing modules `drop_privileges`, `md5` and `sqlite3`.

What it does not do (yet):
* Encryption
* Support receiving big files
* Writing cookies
* Remove virtual hosts (and interfaces) on the fly
