Re: Strange HTTP requests

My guess is that the person requesting these is building or using a
HTTP Request library / plugin which generates random user agents. From
CPAN this is true of PoCo::Client::HTTP which they may be using or
something related.
http://search.cpan.org/~rcaputo/POE-Component-Client-HTTP-0.75/lib/POE/Component/Client/HTTP.pm

"If a UserAgent header is not present in the HTTP::Request, a random
one will be used from those specified by the Agent parameter. If none
are supplied, POE::Component::Client::HTTP will advertise itself to
the server."

It's making about 8-10 GET requests at the same time, then does it again
almost exactly a minute later.

I can't remember seeing anything like it before.
