I have a php script on a domain called domain1.com/post_data.php . This script makes an AJAX call to another script hosted on another domain: domain2.com/set_data.php. set_data.php expects some post variables and writes them to a table....everything is working just fine (because CORS is enabled on domain2.com in case you were wondering :)).
My question/issue is: domain2.com/set_data.php starts a session on its end and "writes/reads" the session id from a cookie....where is this cookie stored? Does domain1.com/post_data.php have access to the cookie set by the remote server script ?
I am writing the session id set by domain2.com in a db there and the session id written to the DB by domain2.com does NOT match with the session id written in a cookie on domain1.com (I checked by reading the PHP SessionID cookie on domain1.com).
