This is a starting point to add a documentation of the whole set of APIs and
classes of Predis. The next step will be to actually improve and extend it.
By default the cURL extension does not trigger any error when fetching a
response with an HTTP code >= 400. Changing this behaviour is also useful to
intercept the 403 error generated when executing Redis commands disallowed
on Webdis by using ACLs.
The cURL extension is easily found already packaged for various Linux
distributions, it provides everything needed and it seems to have a lower
overhead compared to pecl_http.
With Webdis it is possible to define some access control rules to allow or
disallow certain commands and one of the possible configurations is based on
plain old HTTP authentication.
I could have rebased the previous branch with master, but since it was only a
single file and its history was basically meaningless I preferred to start
from scratch.
