One difference is that most caches and spiders are operated by people
you _want_ to access your website: caches are just users in disguise,
spiders are usually search engines that (in general) you want to
access your site. If you're not a Phorm customer, Phorm are just
bandwidth and resource leeches.
For example, if the implication that the URLs are spidered by Phorm
offsite (ie not synchronous with the user access) anyone operating a
UK website is going to need to double their bandwidth, as every page
will be fetched twice.
The IP numbers of Phorm's servers will be trivial to locate: you just
access a website you control from an infected ISP and look at your
logs. After that, blocking is easy.
One thing I'm concerned about is that we operate several low-security
portals where we pass passwords in non-hhtps connections, with the
source IP number thrown into the mix. ie you have an account which is
a username, a password, and a source IP number you need to come from.
It's legacy ware, from back in the days when https was a resource
pig. Presumably Phorm are planning to capture passwords and fetch the
URLs from our origin servers?
