how to ignore certification verification

couple of questions:

Q1 : is there a way to ignore the certificate while making the http request?
Q2 : is there a way to get a cookie by name ? been using a hack ` response.headers.valuesOf("Set-Cookie")[1].split(';')[0]`
Q3: is there way to add special headers to request

suggestion : could you please make `print` as part of the official documentation? I took me a while to figure that one out.
( I had to search to issues log to figure that one out)

print("s0",client.global.get(my-cookie"));
