the ica protocol is not human-language based, so you'll be hard-pressed
to get anything out of it with http commands.  it uses (if unspecified
at install) the system-default encryption level - which is typically
56-bit on freshly staged machines.  for the most part, the protocol itself
is fairly secure, maybe you should try another route?  more recently
it's come to focus that the client-side is somewhat vulnerable.  you've
already identified a web-service.  considering it's used to distribute
an ica configuration to the citrix client, what routes are available
through compromising it.  have you looked at the ica(err. ini file)-file?
 it's plain-text.  does it allow for other types of attacks/manipulations
(ie. hostname/ip => dns poisoning/route modifications).

for what it's worth, here's a somewhat-outdated link with some information
on a few citrix command-line utilities used for querying against a master
browser.
