Setting cookie on remote machine (web service?)

[tphethean]

Is it possible to use a web service to set a cookie on the domain that the web
service is executed on? I need to set a cookie for siteA from siteB, and then
be able to recall the value of the siteA cookie from siteB at a later time.
(both of these sites are under my control so if any special configuration is
needed to do this then it is do-able).

I don't think so. If the web service is operating "behind the scenes",
meaning that the browser never directly calls it as a URL, then I don't think
you could set a cookie from that domain. They only way you could share the
cookies is if the two sites share a root domain name and you have domain
cookies activated....but you still would have to have the browser visit both
sites I think.

So siteA is making a call to siteB, right? If you do a cfhttp from a to b, the
respsonse headers will have all the cookie values (after the cfhttp call, dump
the cfhttp variable to see what i mean). You can parse these out and store
them somewhere so they will persist, say a text file. Then on subsequent calls
to siteB, you would need to set these values in the request header, using
cfhttp again you can set header or cookie values using cfhttpparam. (Using the
values from the above text file) The web service on siteB would just set the
cookies and read the cookie values as it normally would. I use a similar
system for some scheduled task calls, where I need to have the scheduled task
be the same user/login to another server across multple scheduled task. The
tasks actually run through a wrapper, that has a cfide/cftoken hard coded,
those get put into the header before my cfhttp call to the other server.
Hence, I have the same user (cfid/cftoken) making calls to the other server.

byron1021, that idea sounds workable so i will give that a try. Mind if i post
back here with any questions? Regarding the order of the calls, they can
happen either way. we've effectively got 3 sites (more to come) which share
authentication method via a web service on central authentication domain.
Session data is then stored in a database to persist the sessions, but to get
at the session data i need all the sites to be able to retreive their session
id. (I could pass it through url or similar, but this would mean you couldnt
just browse to the site and would have to follow routes we defined - also not
too secure).

Ok i'm trying this code: <cfhttp method='post'
url='http://testcold7.ifslearning.com/cftest/session/cookie.cfm'> <cfhttpparam
type='cookie' name='mycookie' value='#mylogin.sessionid#'> </cfhttp> where
mylogin.sessionid is the value of a structure i want to store in the cookie.
However it doesnt seem to be setting any cookie when i call it - any ideas?
