Is this a valid request?

[lists at lazygranch.com]

I keep my nginx server set up dumb. (Don't need anything fancy at the
moment). Is this request below possibly valid? I flag anything with a
question mark in it as hacking, but maybe IOS makes some requests that
some websites will process, and others would just ignore after the
question mark.
