I guess I'm not a fan of really long prefixes... I've complained before to other people so don't feel special. Prefixes are something that people add without thinking as if they always make the code better and I do blame JAVA influence for this...
The "_interface" really doesn't add anything because that's always the first parameter that we pass. It's just filler.
I think "try" is better than "request" probably. Request is regularly used as a noun and try never is.
But I don't care at this point.
