Recently our web service provider changed its web site platform HTTP to
HTTPS and before  we got some data from the internet site with our web
service( XML )  affter the changes somehow our code doesn't work. When we
call the link via internet browser everthing works well but if we connect
the site via our web service we cannot get the info from them.

Is there any differences getting the data from the internet site via
webservice between http and https ?

any advice would be helpfull

Thanks
