mod_http_oauth2: Record hash of client_id to allow future verification
RFC 6819 section 5.2.2.2 states that refresh tokens MUST be bound to the
client. In order to do that, we must record something that can
definitely tie the client to the grant. Since the full client_id is so
large (why we have this client_subset function), a hash is stored
instead.

**NOTE:** XMPP compression has unresolved [security concerns](https://mail.jabber.org/pipermail/standards/2014-October/029215.html), and this module has been removed from Prosody and renamed. While the bandwidth usage of XMPP isn't that much, compressing the data sent to/from your server can give significant benefits to those on slow connections, such as dial-up or mobile networks. Prosody supports compression for client-to-server (if your client supports it) and server-to-server streams using the mod\_compression plugin. # Details mod\_compression implements [XEP-0138], and supports the zlib compression algorithm. ## Dependencies The XMPP protocol specifies that all clients and servers supporting compression must support the "zlib" compression method, and this is what Prosody uses. However you will need to install zlib support for Lua on your system. There are different ways of doing this depending on your system. If in doubt whether it is installed correctly, the command `lua -lzlib` in a console should open a Lua prompt with no errors. Debian/Ubuntu : `apt-get install lua-zlib` LuaRocks : `luarocks install lua-zlib` Source : <https://github.com/brimworks/lua-zlib> # Usage ``` lua modules_enabled = { -- Other modules "compression_unsafe"; -- Enable mod_compression_unsafe } ``` ## Configuration The compression level can be set using the `compression_level` option which can be a number from 1 to 9. Higher compression levels will use more resources but less bandwidth. ## Example ``` lua modules_enabled = { -- Other modules "compression_unsafe"; -- Enable mod_compression_unsafe } compression_level = 5 ```
