Hi,

Is there a good plugin that is able to block query (like PUT, POST,  
DESTROY) from open proxies, such as in Wikipedia? With something a  
database of blacklisted IP… it would be cool.

Thanks.

Don’t know of a plugin per-say for this exists, but the first google  
result for “rails ip blacklist plugin” spells out exactly how to  
implement on (you’ll then just need to screenscrape a proxy list or  
something similar). However, I’d think it’d be better to handle this  
at the webserver level rather than waste CPU cycles, database reads,  
and memory by handling this in your app.
