mod_http_oauth2: Record OAuth software id and version attached to tokens Unsure if these are used anywhere, but `software_id` is supposedly more unique than `client_uri` which can vary by registration or something? Software versions can also be good to know e.g. in case there is a security issue affecting certain versions that could warrant revocation of tokens issued to it.

This module lets you block connections to remote servers at the s2s
level.

``` {.lua}
modules_enabled = {
    -- other modules --
    "s2s_blacklist",

}
s2s_blacklist = {
    "proxy.eu.jabber.org",
}
